webBikeWorld 2006 Motorcycle Product of the Year

Battery heated clothing is a revolutionary product category that will dramatically change motorcycling for the better. We remain impressed with the Jett Heated Vest, especially now that winter has truly arrived.

Based on our evaluations of three other battery heated vests, the Jett is the hands-down winner. It wasn't originally designed for motorcycling, and the battery and switch location could be improved, but overall, it's the standout product of the year.

The Jett battery heated vest has knocked all other heated vests out of contention. 

It does not use wires to produce the heat, works great for any type of outdoor event, and the battery gives you a real freedom that makes all of the other wired motorcycle heated vests obsolete.

Add in the fact that the vest is reasonably priced, plus a special offer for 2 batteries and you've got a real winner!

Jett Heated Vest proves its worth in 2005 Sydney Hobart Yacht Race

The vest was trialed by Cameron Mead on the Melbourne based yacht ICEFIRE.

Cameron MeadThough this year’s race was a relatively easy race due to mild weather, on the night of the 28th December the temperature dropped dramatically as a strong cold front moved through Bass Straight with winds to 55 knots. As the yacht raced down the face of waves and ploughed through the wave in front, conditions on board the yacht became very wet and cold, especially in the early hours of the morning.

Even though I had sufficient ‘wet gear’ (ocean racing protective clothing) on, I was totally saturated, inside and out and after 4 hours was suffering mild hypothermia.

Time to try out the Jett Heated Vest! After my 4­hour watch I went down stairs, cold and shivering, stripped off the wet clothes and put on dry jocks and tee shirt with the Hawaii vest over the top and turned the vest on.

Within 5 minutes, the other crewmembers onboard could not believe that I was warm and feeling a million bucks, ready to climb into my bunk for a nap before my next watch.

On my next watch, I wore just the Vest, tee­shirt and jocks under my wet gear (which was now totally wet inside as well) and could not have been happier. Though water was still washing down through my neck and filling up my sea­boots, I was sitting there warm as toast and feeling energetic while the wet and cold conditions was sapping energy out of the rest of the crew.

After our watch, the vest was shared around between the crewmembers to get warm, which proved to be a great rejuvenator in both energy and stamina.

My overall assessment on the Jett Heated Vest

Brilliant! – I won’t be doing another yacht race with out it!

The rechargeable battery pack lasted for over 6 hours on the low setting, which was plenty warm enough (55° C) to keep me warm, energetic and mentally enthusiastic to perform my job. I must admit I was surprised that the vest functioned with so much water flowing through it, but it did faultlessly. I found the vest to be lightweight, comfortable and easy to work in. I’m now looking forward to those cold, wet nights ocean racing. – Cameron Mead Review

Jett Battery Heated Vest Review
Heat up without plugging in
By Eric Bass, Jan. 21, 2009, Photography by Jackie Bass

Heated vests are nothing new. In fact, battery-tethered vests, socks, gloves, etc. have been a cool-weather staple of wussified girlyman motorcycle riders for years. Oh sure they keep you warm and comfortable, and enhance both your enjoyment of the riding experience, and your safety due to improved concentration. But in doing so, they rob you of the seminal character building experience of forging ahead through miles of Mother Nature’s fiercest wrath while chattering teeth grit hard against the elements. Until a man has spat into the wind and had it come back at his face as a snowball, until he’s heard the angelic wind chime-like timpani of icicles rattling in his armpit hair, until he’s tasted the salty slimy suffering of un-reachable boogers dripping down into his mouth, can he truly call himself a man.
Fair reader, I think not!
So at this point you’re probably saying to yourself, “Well then tell me, Mr. More-Hardcore-Than-Thou Survivor-man, why am I reading, what I assumed until now, was your test and review of a Jett heated vest?!” Amigo, that is a 100 percent valid question, and of course, I have a 100 percent dumb-ass answer for you. Ever since I was a kid I was always obsessed by those completely-off-the“cool-o-meter” rocket powered “jet vests” that military flyboys would use to magically float down onto the 50-yard line of the Super Bowl. doesn’t typically employ felons, but, hey, times are tight! This criminal-looking character is wearing the Jett Battery Heated Vest, a quality product not associated with criminals. doesn’t typically employ felons, but, hey, times are tight!

The primary heating element is located in the back of the vest. EBass sez it works wonderfully.

You can imagine my stunned disappointment at tearing into the suspiciously under-sized package that arrived at my doorstep, to find that the “jet vest” that I thought I had ordered, turned out to be a lowly heated vest made by a company called “Jett.” Now I have to confess, I found that this self-contained space heater dealio is a heckuva well thought-out piece of kit. That is, for any folks out there who are, into that sort of thing. The heating element itself runs along your spine and shoots far infrared (FIR) energy into your back meat. Jett’s website claims that this not only feels good (which I’ll vouch for), but that it’s good for you as well (which I won’t). Turning on the vest feels almost as nice as wiping your face with one of those hot moist towelettes they give you at fancy sushi bars to help you mellow out before you chow down , except it isn’t moist, and it’s on your back, and nobody shows up to bring you food afterwards. Pity.

The Jett vest comes with a three-step thermostat controller that pokes out from beneath your jacket to let you customize your confines to temps of 104, 122, or 140 degrees. Now, after years of cultivating a carefully sculpted insulating layer of adipose tissue, I found that my well-marbled physique never required more than the 122 degree setting, but individual results may vary. Rest assured though, you can forget all about the conventional wisdom that says Lithium batteries don’t generate enough heat relative to tethered systems. I’m here to tell ya’ that 140 degrees worth of FIR is more than enough to defrost the knobby bones of even the most blubber-impaired rider. 

The Jett vest’s battery stores all the power you’re likely to need, generating a total output of 14.8 volts (30 Watts) and holding a charge that lasts 4-8 hours depending on the heat setting. The power pack is somewhat bulky and tips the scale at just over half a pound, so it ain’t like stuffing a couple AA’s in your pocket. It fits snugly into a Velcro pouch near the hip, which necessitates a bit of shuffling to settle ergonomically in a tuck position, but not a big deal. According to Jett, the batteries are made of soft poly materials, and allegedly won’t overheat or explode, even when impacted or submerged. In fact, the entire vest is waterproof and even washable with the battery removed.

Since the Jett vest doesn’t require a harness to your motorcycle battery, you’re free to use it anywhere you go, making it a more versatile and useful investment of your hard earned dinero. It also eliminates the need for uncomfortable bulky garments while riding. A long-sleeve winter thermal shirt and the Jett heated vest are really all you’ll need for most riding conditions. 
So there you go - while it may not aid in your character development, or goose you onto the 50-yard line of the Super Bowl, the Jett Battery Heated Vest will at least obviate the need to plug into an electrical IV drip every time you saddle up like some drooling geezer on life support. And until I can get my hands on one of those high flyin’ hydrogen peroxide fueled Buck Rogers jobs, that’s just gonna have to be good enough for now.

Battery Powered Heated Vests, Are They Worth It?

The Right Heated Vest Will Make Your Trip a Good One

D. Goossens Yahoo Contributor Network
Dec 31, 2008
As a 50-year-old motorcycle enthusiast in Central Ohio, I have noticed my tolerance to the cold has diminished over the years. I used to ride wearing a hard-wired heated vest that plugged into the battery on the motorcycle, but I found that the cord seemed to always be in the way.
When I spotted the new battery powered vests on the Internet 3 years ago, I figured that was the answer, so I immediately ordered one of the carbon fiber heated vests from a large catalog house. This vest worked well for one year, but the batteries only lasted for 4 hours, so I made sure I was within range of my home before the batteries gave out.

The second year of use, I found the batteries had dropped to holding a charge to only 1 hour and the vest was starting to break wires which I had to solder together several times to keep the vest working. I am guessing that as the vest is used, the wires get fragile from the heat and break easily. As the cold moved into Central Ohio this fall, I found the vest batteries were almost done and the wires snapped again as soon as I put it on.

I turned to the Internet and found 2 companies who make battery operated heated vests and ordered one vest from each of them.
The Gerbing Lite vest arrived first and I was immediately impressed with the quality and the features in the design. This heated vest has 2 heat pads in the chest area and one in the back. The battery unit is located in an inside pocket on the left side and is accessible by unzipping the vest and pulling the battery from the pocket and turning the vest on. You can set the level of heat you want and on high, it lasts easily over 8 hours. The battery is a little bulky but you get used to it quickly.

The second heated vest I ordered from Australia called the Jett Vest. This vest puts out some serious heat even on low! It has one large heat pad in the back and when you turn it on, that vest is warm within seconds. The Jett vest is a quilted material and is warm even with the vest turned off. The battery pack is in the right inside pocket, but the controller hangs below the vest for easy access to change the heat level. I have been getting 6 hours plus on the battery use.
The only drawback to both of these vests is the lack of pockets. The Gerbing and the Jett both have 2 hand pockets, but I would like an additional inside pocket if they could.

For everyday wear around a cold house or office, I prefer the Gerbing as it is lighter weight and seems more flexible. The Jett is my favorite for cold weather motorcycling as it definitely produces heat, but only on your back. These two companies should get together and combine their designs, you would have the perfect heated motorcycle vest. 2006 Jett Battery Heated Vest Review

by Rick K. for

Finally -- nice warm heat without wires!
This must be the Year of the Heated Vest!

And just in time, because the frost is on the pumpkin, as they say, here in the Mid-Atlantic U.S.A. (translation: it's October and it's starting to get cold!).
The EXO2 StormRider heated vest remains a big hit around here.
Just as I was thinking about dusting it off and installing the StormRider's controller on the GT1000, along comes the Jett battery heated vest to save the day.

webBikeWorld visitors will remember that weren't very pleased with some of the other heated vests we've reviewed for a variety of reasons.
These included hot spots caused by internal wiring to the amount of power that they draw to the pain of installing the wiring harness and having to mess with mounting the controllers.

Besides that, some of the manufacturers actually charge extra for a controller, believe it or not!  That's like buying a motorcycle and having to pay extra for the handlebars and throttle.

I held out a hope that some day technology would come to the rescue, and that day has arrived, for the Jett battery heated vest is completely self contained, powered by the latest in rechargeable battery technology with a two-unit lithium-polymer battery pack.

Wireless Heat
Think about it -- no more wires, no more wiring harness, no accessory controller, no mounting problems and no drain on the motorcycle battery! The four 3.7V lithium-polymer waterproof batteries are only 173 mm long by 55 mm wide and is a mere 11 mm thick ( 6-3/4" by 2-3/8" by 7/16").

Yes, the battery pack does weigh 273 grams (9.63 oz.), but it fits nicely into a Velcro-covered pocket inside the right-hand bottom portion of the vest and the weight isn't a problem.

(Note: We originally listed the Voltage for a single battery but in fact each battery is 3.7V and there are 4 of the slim 3.7V batteries in each vest battery pack for a total of 14.8V (4 x 3.7V). The dimensions and weight for the battery pack are correct. See the comments section at the end of this page for more information on the batteries).

The battery pack has a single wire that attaches to a provided 120V (for the U.S. market) charger. The battery was almost completely charged when the vest arrived, but a full charge took about 2 hours or so. The good news is that the battery lasts a long, long time and the vest puts out plenty of heat.

The heat seems to come on almost instantaneously, which is a real surprise. Switch on the vest and instant heat!  I've worn the vest for a measured 6 hours, alternating between the medium and high settings, and the battery was putting out warmth the entire time.

Jett claims that a single battery will last up to 4 hours on high, 5-6 hours on medium and up to 8 hours on low (Note: corrected from our original posting, which said the battery would last 4 hours), and of course your experience may vary.

Jett Heated Vest Controller
The Jett battery heated vest comes with a simple controller. The vest has a single wire routed right next to the battery pocket inside the right-hand bottom section of the vest; this is the wire that leads from the battery to power the vest. After the battery is charged, the battery wire and the vest wire are plugged into the controller and you're good to go.

The controller hangs out the bottom of the right-hand side of the vest and it's about the perfect length for any of the motorcycle jackets I've worn while evaluating the vest. The controller wires are just long enough to let it hang out the bottom of a 3/4-length motorcycle jacket like the Tourmaster Advanced, the Rev'it Cayenne and others.

The controller has two push buttons; one turns the vest on and off and the other switches between the low, medium and high settings. The low setting reaches 40 degrees Celsius (104F); the medium setting is 50C (122F) and the high setting is a hot 60C (140F).

Believe it or not, the high setting is almost too hot, if that can be possible in a motorcycle battery heated vest. I mostly keep the vest at the medium setting, with occasional forays into the red zone if I feel a chill. Also, the vest seems to heat the back much hotter than the front, but the heat is in the right place, from the mid to lower back, down by the kidneys.

UPDATE:  Jett confirmed that the vest has heat elements only in the back. According to Jett, "this is the correct place to put heating as it is dangerous to have heating directly on your heart or too close, as experience has shown it can cause fainting.

The rear elements will keep upper and lower back warm including kidneys. These are vital, also being "FAR" infared heat (red heat), it is absorbed 90% into the body via the spine and will spread rapidly and safely though your whole body system. Here is a link which will explain the many benefits of far infrared heat.
The selection button cycles through the three heat settings and a small light cycles through green, orange and red to indicate the temperature. The settings are changed by pressing the "off" button down for a split-second and the setting is changed at each press to the next level, starting over again at green.
And here's one of the nicest features of the Jett battery heated vest: I can simply get off the bike and walk away without having to worry about forgetting to disconnect the wires to the bike's wiring harness. And, the vest keeps working -- in fact, I've taken to wearing it around the house, outside, on hikes and other adventures... It works great for any type of outdoor event, and it's a real freedom that pretty much makes all of the other wired motorcycle heated vests obsolete.

Another nice feature of the Jett battery heated vest is that it does not use wires to produce the heat. In fact, I'm not sure how it does it, but the vest heats via "Far Infrared Technology", which is claimed to have all sorts of therapeutic benefits, including reduction of joint stiffness and back spasms, pain relief, increased blood flow, and more.

The Jett battery heated vest is available in a wide range of sizes from XXS to XXXXL. Mine is a size large, and although Jett provides two elastic cinch adjusters, one around the chest and one down at the hem to help keep it snug, I'd probably order a size medium if I were to do it again. The large seems just slightly too big for me -- I have a U.S. men's size 43 chest and I'd guess that the vest is maybe a 44 or 44.5.

Sizing Addendum
Read the paragraph directly above again and comments below and note that you may consider ordering one size smaller than normal for a snug fit; other owners have reported slightly larger than normal sizing after ordering the Jett vest.
I think it's important to make sure any heated clothing fits slightly tight to keep the heat as close to the body as possible. Just remember that a heated garment should never be worn against bare skin. I usually wear a thick cotton long-sleeve undershirt underneath and cover the vest with a stretchy turtleneck to keep the vest pressed against my core.

The Jett vest has a zipper up the front and a deep V-neck, so it shouldn't interfere with a motorcycle jacket neck closure or zipper. When the weather gets chilly, I usually wear the vest along with a 3/4-length motorcycle jacket and a neck wind block, like the EDZ MultiTube neck warmer, the Rukka neck warmer or the Frank Thomas Antifreeze Neck Guard.

One of the nice things about wearing a heated vest is that you can usually get away with fewer layers under the motorcycle jacket, which provides greater freedom of movement and can actually be safer because you can move back and forth on the bike to check traffic.

The Jett battery heated vest is actually very reasonably priced at $275 Australian dollars, which equates to about $206.00 U.S. dollars. Jett charges $30.00 Australian (about $22.00 USD) to ship worldwide. But wait, there's more

I'm really glad to be free of the wire, the controller installation, the battery harness and the charging problems associated with all of the other motorcycle heated vests we've tried.

The Jett battery heated vest has knocked all of our other heated vests out of contention and it has the added benefit of providing warmth during many other off-bike outdoor and indoor activities. Add in the fact that the vest is reasonably priced and the free extra battery pack offer and you've got a real winner!

More on Battery Heated Vests
We recently purchased two more battery heated vests for evaluation; One vest was from Brookstone, a popular catalog retailer, and the other was from Hammacher Schlemmer. Our opinion is that the Jett vest provides the most reasonable solution for motorcycle riders in need of a battery heated vest.

Your Comments and Feedback

From Jett Heated Vests (2007): "We use four 3.7 Volt, 3 Amp Lithium Polymer Batteries in series to make one battery pack, which gives us a 14.8 total Voltage. The Wattage & power varies depending on which heat setting temperature is drawing the heat & cannot be compared to conventional means which use metal wires & also by implementing a Thermostat, gives us the ability to conserve battery power, similar to your central home heating.

Once the desired temperature has been reached the power cuts out & restarts as it drops to program level. Size of Batteries is always getting smaller & we will be replacing batteries with smaller types as they become available. We hope to supply Batteries half the current size in the next 12 months.

Batteries are perfectly safe and also fitted with Overcharge Protection Circuit which protects from overcharging -- you can leave on charger for months without any danger. Also the polymer batteries do not explode like their hard cased counterparts –- they merely “puff up” like a soft pillow if damaged, even if dipped underwater. Hard cased batteries have been known to explode if exposed to water!"

From Ben B. (3/09):  See this special report on modifying a Jett Battery Heated Vest to provide front heat for hyperthermia treatment for cancer.

From "D.J.":  "I have had the Jett vest for over a month, and I think it works very well. The batteries ability to power the vest for prolonged periods is phenomenal. No doubt, riders winter riding needs are extremely idiosyncratic, varying with metabolism, circulation, cold sensitivity, the bike ridden and its unique pattern of wind blast, other garments, etc. I also have a Widder with arm chaps.

If I am looking at a longer ride below 40 degrees, its Widder Time. If I am looking for some comfort on a chilly day, on goes the Jett, if its not already on. I am 64, smoked 2 plus a day for 34 years, and don't have the best circulation in the world. I don't have to be on the bike for my old bones to really appreciate the comfort that the Jett can provide, working outdoors, or even just around the house if the temp is in the teens. I wear it under an Aerostitch, well layered.
I ride both a BMW RT and a Honda VFR. Skin out starts with a cotton tee, then Patagonia polycapilene long sleeve, then the electric vest, then a light fleece, then a $12 First Gear membrane liner, very thin, that is wind and waterproof, then the Stitch. The layers are the same using either vest. If I were to loose a layer, it would definitely be the cotton tee. You know the hikers adage, cotton kills.
I would say that the $12 liner is a big key for me. I got the liner initially as a waterproof layer for under a mesh Sidi hot weather jacket. However, I have used the liner much more in cold weather. The liner goes on before I need any electric or battery vest.

Even though MY Stitch is waterproof, it is not quite windproof. The liner is. That liner makes a huge difference to my cold riding comfort, partly wind blast, and partly I suspect, vapor retention. Ask any physicist about the amount of energy that can be carried off by latent heat. This is exactly what happens when vapor around your body is lost. A fellow named Stephenson, ex NASA engineer mfg'd some pretty exotic backpack gear as Warmlite, maybe still the best. He was nearly religious about preventing the loss of body moisture to conserve body heat.

I will admit that when I first received my Jett, I was disappointed, felt mislead when I discovered that there were only two 5" square heated patches, and intended to return it. But after trying it, have certainly changed my mind.
Freedom from the umbilical to the bike is nice. The use off the bike, and when going from bike to bike, to maybe a bike without the right outlet are definite pluses. For me, esp on the RT, that little glow of heat in the small of my back is often just right. On the VFR, I want more heat sooner. If I were smaller, rode more tucked in, and ran a hotter metabolism, maybe not.

I have tried to independently verify some of Jett's info or claims regarding Far Infra Red (FIR) penetrating heat, being NASA derived, increasing blood flow being right over the kidneys, and having multiple health benefits, all without much success.
I did find one medical study that pretty much discounted all such medical claims (not just Jett) with the exception that arthritis sufferers find relief in the heat. Just my taste, but I would be as happy not having read the extensive medical claims without authoritative data to back them up.

Regarding the arrangements, I think the battery should definitely not be in the back. Also, with the Velcro arrangement and quite a bit of cord, you can arrange the control fob about where you want it. On the left would be OK, but what is overlooked, and not well explained, is that this vest has a built in thermostat.
When I run the Widder, I am constantly at the switch like every 2 to 4 minutes, too hot and off, now its cold and back on. The Widder definitely needs a thermostat too. But with the Jett, just turn it on and let it do its thing. I have never used other than the first level of heat, level 2 is just too hot for me. You may not be able to select among heats 1, 2, or 3 by feel, but if you can't turn it off and on by feel, maybe you shouldn't be riding.

What might be nice would be a little stiffer fabric or something around the battery pocket. The battery has a little heft, and the battery pouch just feels a bit floppy. Also a bit more massive Velcro tab to help hold the fob and cord in position would help.

All in all, I think this is a pretty amazing, if controversial product. Judging from your other battery vest reviews, Jett is obviously doing something right where others have failed.

One thing puzzles me however, is why after all the reviews of heated vests, some of which are obviously totally unacceptable, webBikeWorld has not reviewed Rider warehouse' Kanetsu products, surely among the most innovative electric gear available today. Something's going on. Is Andy not playing nice?

Whatever, I definitely appreciate what you guys are doing. I have bought a number of items that you have brought to my attention. I am just about to the point that I buy absolutely nothing without an extensive professional review. In the moto world, that is you guys, MCN, and road tests. Keep it up, please."

Editor's Note:  Thanks for the kind words!  We just haven't gotten around to the Kanetsu line, but I'll add it to the shopping list.

From "J.A.":  "Thanks for testing the Jett vest. The concept of battery powered heat is interesting but for riders like myself it would be almost completely useless.

First, this vest has no heated collar. The carotid arteries are the perfect place to transfer external heat to your blood supply. If you can't proactively heat your neck you're not going to be warm enough in extremely cold ambient temperatures. You're not going to be very comfortable either.

Secondly it's not difficult or complicated to wire a proper power socket for heated gear. It's not expensive either. I have to rely on my heated gear to work ALL the time. I can't afford to have it crap out after 4 hours or 40 hours for that matter. It must be capable of full power at all times period, no matter how far from home I ride or how long I'm gone.

I don't need to fill my tank bag with spare batteries that may or may not work when I need them, nor do I want to be changing out vest batteries even if it's only every 6 hours.

And no heat in the front of the vest?  That's just silly. That's precisely where you're being pounded by the cold air. Sure that helps the batteries last longer but who needs batteries?  Just plug in a proper piece of purpose-built motorcycle gear and you're covered. You say this vest was not designed for specifically for motorcycle use. That's pretty clear. The features (or the lack of features) are good reason to leave it for bird watchers, not riders.

And you don't need a huge, high-capacity alternator to run a proper piece of heated gear. Sure a full liner like Gerbings might draw 70 watts or more but a good vest, Widder to name one, is only pulling half of that. In addition to "big bikes" I've run my Widder very nicely on an 80cc Honda scooter.

I routinely use a Widder vest on my KLR 250cc and it gets nice and toasty with a simple on/off switch. Also even if you do have a serious electron shortage, just use a controller like the Heat Troller which is non-resistive. Only take as little juice as you really need at any moment.

You might love the Jett vest but I'd give it thumbs down for motorcycle use at least here in the mountains of NH. It wouldn't cut the mustard up here on the 45th parallel."

Editor's Reply:  I'm not sure how to respond to your comments, because it's not clear to me if you've actually worn a Jett vest and compared it to various electric vests?  We have - if you look through the webBikeWorld reviews, you'll see that we've evaluated several vests and jackets. So I think we have some pretty good data to make our comparisons.

Regarding the issue of a collar: although they may exist, the heated vests we've seen do not have a collar that would cover the neck and carotid arteries. All of the heated vests we reviewed and all of the heated vests I've seen in my recollection have a shallow or V-neck, which is typical for motorcycle vests.
Most motorcyclists I know do not want an extra collar binding up an already tight collar on most winter motorcycle jackets, and that's the reason why most motorcycle vests do not have a collar.

Regarding the heating elements in the front: Having heating elements in the front of the vest just doesn't seem to make much difference to any of our evaluators as we compared the different vests.

A heated vest with heating elements in the front doesn't necessarily mean the vest is better or puts out more heat, because not all electrically heated vests are equivalent. Some are worse than others - we found that in our experience, the Chilli heated vest was not as efficient as other vests we have evaluated, battery operated or otherwise.

The point is that comparing heated clothing solely on the basis of the number of elements it contains or whether it is battery powered or if it plugs into a motorcycle's electrical system is not necessarily valid.

By the way, Jett recently told us that they've had such a high demand for the vests from motorcyclists that they are developing a motorcycle version that does have heat in the front.

Regarding electrically heated vests: We had electrical problems with at least one of the heated garments we tried. Motorcycles don't always have powerful and perfectly operating electrical systems that are designed to operate heated clothing. This problem is exacerbated if the rider is also using GPS, radio, auxiliary lights, etc. that are also wired into the bike's system. From the emails we've received, it's apparent that electrical system issues are common for riders who use electrically heated clothing.

Also, it's very easy to carry a spare charged battery or two for the battery heated vest, which can give 6, 12, 14 or more hours worth of heat. I'm not sure how many riders need a flow of heat more than 6 or 7 hours straight.

And just because a heated garment plugs into a motorcycle's electrical system doesn't necessarily mean that everything will work without problems. There's always the issue of having a blown fuse, a short, water in the electrical system, etc. in addition to the load on the battery.

So the point here is that it's not that easy to make blanket statements -- there's always a compromise. We did mention that battery heated clothing technology is in its infancy, but it's our opinion that battery technology is rapidly evolving and battery heated clothing will have a huge impact on the motorcycle market.

We never meant to imply that a battery heated vest will alway put out more heat than an electrically heated vest - in fact, our evaluations of other battery heated vests show just the opposite. We do think that the technology is making a huge impact in motorcycling however, and that's a great thing for all of us.

From "A.":  "Thank you for your excellent and informative review of the Jett Heated Vest. I ordered one for my wife a few weeks ago, and she's been nothing but happy with it since. She rides year-round in the Pacific Northwest, and this vest has been a huge boon to her comfort and safety level.

We mentioned WBW in our order, and they sent along a second battery free. Unfortunately, one of the two batteries was defective. I emailed the company, and they shipped us a replacement the next day, no questions asked. That blew my mind, and made me feel very comfortable dealing with them; and trusting you as a no-nonsense source of valuable information. Keep up the great work."

From "L.S.":  "I received my Jett Battery Powered Vest and had a question about the fit. When I put it on, it looks good in terms of fit (no bagginess, gaps under the arms, etc.). The only thing is there's just enough looseness around my abdomen that when I zip my winter jacket up, there's a tendency for the vest to bunch up.

Its not a big problem as I usually just reach in and smooth out the material before zipping the rest of the way up. I also will hold off cinching up the velco waist bands (its a 3/4 lenghth jacket) until after I'm zipped up.

My question is - Is this an indication that I should have gotten a smaller size?  I purchased a medium and its hard to believe I should wear a small but maybe so."

ditor's Reply:  As we reported in the article, I usually take a large but should have ordered a medium, so possibly you could have ordered a small. .... I guess I wouldn't worry about the front bunching up, mine fits loose also, as long as the vest provides the heat in the back.

Since we published the Jett article we have received several emails from other battery heated vest vendors asking if we could try theirs also -- I didn't know there were so many -- and we're currently in the process of evaluating 3 more brands.

From "E.W.":  "Thanks for the review. The vest was just what I wanted/needed. I like not having things attached to bike when I ride.

I ordered an XL and when it came found that it was too big. I contacted Jett via email and within hours thay responded saying that they would send (via Australia Express Mail) me large and wait till I got before sending back the XL (they would even reimburse me for shipping). I got it inside of a week.

Jett has great customer support too bad all online companies aren't this easy to work with."

From "D.B.":  "Even though It's between 6 and 8 degrees Celsius here in Vancouver every morning lately, just the other day I decided not to put my bike into winter storage, and instead, continue riding all winter this year. I'm just not emotionally ready to give up riding and return to driving this year.
So, it was with great interest that I read your review on the Jett Heated Vest. I had been considering buying a heated vest for quite some time and this one seemed to fit the bill.

I had a little bit of difficulty ordering online, as their secure server did not seem to be Mac friendly. I sent Rob at Jett an email pointing this out and he responded by telling me that they would look into this as quickly as possible. It didn't matter however, as a few minutes later the phone rang and it was Rob calling me from Australia to take my order personally. One pleasant conversation later, I had ordered a medium, based on Jett's sizing chart (I have a 42 inch chest). It arrived here from Australia in only 5 business days and was a perfect fit!
I have to say that I am very impressed by this vest. The heat comes on immediately, and there is plenty of it! Riding to work in 8 degrees,  I only needed the vest on it's lowest setting when worn under my Belstaff Mercury jacket.
The biggest advantage of this jacket over traditional heated vests is that it can be worn in so many environments, not just while plugged into your bike. I work in the film industry and spend a lot of cold winter days, and nights, working outside. This vest and I are going to be spending a LOT of time together!
Thanks again for running such a great website and yet again pointing me towards yet another great product that I would have otherwise been completely unaware of. And of course the extra battery offer didn't hurt either!"

From "R.M.":  "I'm attempting to return the vest for a refund after trying it out this morning. The vest only has two 5" square heating elements, and they do get quite hot, but this won't do the job on an unfaired bike. My back was nice and warm this morning, but the front of my torso was quite chilly.

The controller is not well designed for motorcyclist either. Wearing my 'Stich, I could reach into the side opening of the suit to touch the controller, but could not tell what button I was pressing with gloves on. I was forced to pull over, pull the suit around enough to get the controller to be visible, so I could see what I was doing to change temps, or even turn it off.

I hope other readers are not as disappointed since your review made it sound very appealing. It sounded like the perfect vest for my Supermoto, which would strain to support heated grips and a wired vest together. But with no front heat, I just can't see this working with an unfaired bike.

Hopefully I'll just have to eat the overseas shipping both ways, and can get the rest of my money back."

Editor's Reply:  Sorry to learn it didn't work out for you. I use it all the time when riding my unfaired Ducati and the medium level heat on my back works out great for me when I'm wearing a windproof vest or jacket.

The controller sticks out the bottom of the 3/4 length jackets I've tried it with and I can access it fine with my right hand, but I did suggest to Jett that they move the controller to the left hand side. I find that I only usually set it once for medium heat and leave it at that, it doesn't need much adjusting.

If you don’t already have one, you may want to try a windproof vest or pullover. I mostly wear the Rev'it Cayenne jacket in the winter and it's completely windproof with the zip-in liner and very warm with the zip-in liner, I think it's much better than the Aerostich Darien, which I sold because it basically was not windproof or waterproof at all (I think they are highly overrated and there are many better choices nowadays compared to when the Aerostich was the only game in town).

Follow-up From D.B.:  "Wore the vest ALL day today. Got to love having two batteries.

I also wore a watch with a stopwatch today. I turned it on when I put the vest on. Would you believe it? The vest lasted around 7 1/4 hours with its time divided equally between the medium and low settings!

Try as I might, I just haven't been able to use the high setting, too hot!  Maybe when the temp drops below freezing, but I doubt it.

I have found one thing that I consider to be a design flaw with this vest; the battery location. 2 problems. First, it is just not comfortable there. When wearing it standing up there is too much weight to one side. But that is very minor compared to the the fact that when sitting on my bike, a cruiser, it gets wedged between my hip and thigh bones. Not too comfortable.

I think that the battery should be located at the rear in the middle and down fairly low. I spoke to Rob at Jett about this but he disagrees. I am going to re-locate the battery pocket in my vest.

All of that being said, none of that has diminished my love of this vest one bit. It's hard to take it off."

Editor's Reply:  Thanks for the additional feedback, I actually just had some correspondence with Jett asking about the battery location and also the wire location for the controls. I thought also that the battery should be in the rear, although since the vests are used by many non-motorcyclists, that location may not be comfortable for sitting in a chair.

I suggested that the controls should be placed on the left side for motorcyclists, so we don't have to take our hands off the controls. They were open to the suggestions and talked about the possibility of redesign or making a motorcycle-specific version once he got a feel for the motorcycle market.

I should have mentioned this in the original article... 2007 Jett Vest Update Report

Jett Battery Heated Vest: Take 2
by Rick K. and Kim C. for
Editor's Note
We reviewed the original Jett battery heated vest in October 2006. Jett made a few changes to the 2007 version so we decided to post this report.

Jett Battery Heated Vest - Front View

The original Jett heated vest was a breakthrough. It allowed motorcyclists to stay warm without wires! We've been predicting the eventual dominance of battery heated motorcycle clothing ever since.

There are two advantages to battery heated clothing. The first and most obvious is the elimination of the wiring harness and controller necessary for traditional heated garments. The absence of a wiring harness gives a sense of freedom and no worries about having to install yet another electrical device on an overloaded charging circuit. It also prevents absent-mindedly walking away from the bike with the heated garment still connected.

The other real-world advantage is the portability of battery heated garments.
They can be used on multiple bikes without having to add a second harness.
Also, a battery heated vest can also be used off the bike, both indoors and out, for general comfort, working in the yard, going to a sporting event, riding a bicycle or whatever.

I've become a huge fan of my original Jett battery heated vest, but I guess that makes me biased.

So when the updated vest shown here arrived from Jett, I gave it to Kim, who hadn't used one before. I figured this would give us a sort second opinion double-check on last year's report.

Jett Battery Heated Vest for 2007
Jett made a few minor changes to the 2007 model. The battery pocket on the original was a weak point, so the new vest has a reinforced design and adds some "hook and loop" to hold the controller in place.

But the main difference is the battery pack itself, which is slightly thinner and 22% lighter. Lighter is better, because the older style battery did make the original vest feel a bit lopsided and slightly bulky when the vest was worn alone, and the weight eventually tore the fabric.

Here's a chart comparing the differences:

Original Battery

Updated Battery


170 mm

170 mm


60 mm

50 mm


12 mm

10 mm


90 g (3.2 oz.)

70 g (2.5 oz.)





The amperage has been slightly reduced on the new model, but not by much. The advertised "burn" time (probably not the best choice of words for an electrically heated vest!) on the original was 7 hours, compared to 6 hours on the updated battery. Remember that the heating time will depend upon the controller settings used by the rider. Extra battery packs can be purchased also.
Every time we publish and article on battery heated clothing, we get a few emails from non-believers. A couple of visitors wrote very long and detailed technical narrations that "proved" that battery heated clothing can't possibly work. I wrote back and asked them if they tried one, and the answer was "no". Amazing...
All I can say is that I've been using the Jett vest for two seasons and it works for me. Sure, it doesn't put out as much overall heat as, for example, the Tourmaster Synergy vest we reviewed recently, but that vest is too hot for me anyway, believe it or not, and I have to fuss with it to cycle it on and off to the "low" position to stay comfortable. I also do not care at all for the feeling of heat on my chest -- it makes me feel short of breath, and I wonder if it's dangerous.

Wireless Heat
The Jett vest radiates heat along the lower back, which is just where I need it, and it keeps me nice and comfy. All I need to do is wear it under a decent 3/4-length jacket and I'm all set. It is important with any heated garment to keep the material close to your body; I usually wear a cotton T-short under a cotton turtleneck, then the vest, and sometimes I'll put a thin polar fleece sweater or windproof shirt over the top of the vest to keep it snug.
To recap, the Jett battery heated vest is rechargeable and has a controller that hangs down from the right side. The controller has 3 levels: low, medium and high. A green light indicates low (40 C or 104 F), orange is medium (50 C or 122 F) and red is high 60 C or 140 F). The vest comes in sizes XS through 4XL.

I usually wear the vest under another garment, such as a light sweater, but I think Jett recommends that the vest is worn as a top layer. The current model does not have elastic on the sides, so it's important to follow the instructions for fitting on the Jett website to get the correct size. As with any heated garment, it's important to keep it close to the skin to transfer the heat.

Kim's Riding Impressions
I felt the heat from the vest within the first minute of turning it on, although I didn't feel heat on the low setting. The medium setting worked best for me. While sitting on the couch, working on the REV'IT! women's winter pants, underwear and boots review (coming soon!). Quite comfortable temperature.
The high setting was too hot for indoors. I was leaning against the back of the couch and the heat became to intense and I had to back it down. I can see how the high setting would be useful in outdoor activities. Too much for indoors with the house temperature set at 73 degrees.

When changing temperatures the change can be felt within a few seconds, which is very nice. The instructions are also easy to understand.  And the vest came out of the box charged and ready for use - instant gratification!

The two lower front pockets are nice but on the small side. With regards to battery life, I put on the vest at 8:20 am and it was still going strong at 11:30.  At 12:00 I noticed a lack of heat, so I took a look at remote and it had turned itself off. The battery needed to be recharged; the specs indicate 240 minutes; the vest was mostly set on medium during this time.

The specifications indicate that it takes 4 hours for a full charge. I started the charge at 12:03 and it was fully charged at 4:30.

With regards to sizing, the unisex XXS fits nicely; I typically take a size 2 - 4 or ladies small. The vest has a cinch at the lower hem and waist and a Velcro patch to hold the controller. The control has an easy two button on/off -- the off button is used to cycle through the low, medium, high heat settings.

There is now zipper access to the battery pack. The 14.8 V rechargeable battery is about 7inches long and 2 inches wide. The lower battery weight makes it comfy; I forget the battery is there after a few minutes when sitting. When I'm walking, I know the battery is there and can feel a little extra weight, but it's not uncomfortable, although I can notice the battery against my leg.

Couple of notes:  the instructions recommend unplugging the battery from the control when not in use. The vest is hand washable (30 degrees C, 86 degrees) after removing the battery and remote and they recommend hang drying.

Your Comments and Feedback

From "D.H." (November 2012): "I purchased a Jett vest shortly after your original review was published. Not much to add: between your review and the reader comments everything has been thoroughly discussed.

I agree 100% about the battery and controller placement, although neither is a deal-breaker for me (these niggles may have been corrected in Jett's new "Riding Vest"; I hope WBW gets one to test).

I ride all winter unless the roads are too icy, and use the Jett on the very coldest days -- from about 30F down to the single digits. With proper insulating and windproof layering, the vest supplies a surprising amount of heat. The vest and its connectors and battery pack are still working as new, and the battery holds a charge for an amazing length of time.

With winter approaching, I recently fished the Jett out of the closet for the first time in 7-8 months. Prior to charging the battery, I decided it would be a good idea to fully discharge it first, something I thought would take maybe 10 minutes. Even set to High, it took a couple of hours to drain the battery!"

From "M.H." (12/09):  "I recently switched from a BMW/Widder wired heated vest to a Jett battery powered unit. I gave up on the wired unit due to ongoing issues with the wires coming unfastened. I also wasn't all that crazy with the simple on/off mode, which called for constant fiddling with the switch (which is a dangerous distraction while driving).

I'm really quite pleased with how well the Jett vest works. Dressed in my 3/4 coat with only a t shirt and the Jett vest underneath, and light gloves I was out early this morning in damp 40 degree weather, riding across the metro area at freeway speeds.

At just the low setting I was quite comfortable. Without the vest I would have been wearing a heavy wool sweater and possibly a balaclava, and feeling very bulky. The Jett vest is noticeably thinner and lighter than the wired vest.

I don't mind that the vest is long, it stays tucked into my riding pants instead of leaving a gap at my lower back. I have mixed feeling about the low neckline: on one hand, it would be nice to have a collar (as does the Widder), and on the other hand, less bulk plus it doesn't get wet and wick moisture the way a collared garment does. Great product!"

From "T.M.":  "I bought a Jett Battery Heated Vest based on the reviews on your site and am more than satisfied.

I am a year round rider in all weathers and predominantly use the bike to commute to and from central London. Having been run over recently by a foreign driver apparently unaware of the fairly universal ‘red means stop’ protocol at traffic lights and having damaged my hand when it got caught in the handlebar cables when I hit the deck and bounced, I have a slight aversion to wires.

My criteria were obviously, that I wanted no physical connection to the bike so it had to be battery and had to have a fairly good battery life. The Jett vest is phenomenal. I couldn’t say if wired products get hotter as I have not used any. I can say it is more than hot enough to keep me nicely warm during zero degree commutes at 4 in the morning in the middle of winter.

The battery seems to last for a good healthy 6 – 8 hours on the medium setting which is ample for a few days at a time. The heat in the lower back really is effective at warming me all over. It’s simplicity in itself to plug in and recharge. I have read comments about the size of the battery pack but it’s not much bigger than a fag packet and weighs no more than a phone in reality.

The remote hangs down below the vest and sits nicely in the front pocket of my trousers. I think I should really have brought a size smaller but again, with a winter riding jacket over the top and the straps done up that all seems to press it nicely against me anyway.

Amazingly, it took exactly 7 days for it to be sent from Oz to the UK and it arrived fully charged and ready to go. It’s a phenomenal piece of kit and there is something quite pleasant about being warm when you leave your house before you even reach and start your bike. Also when shopping in the cold you can take the warmth with you which seems to make much more sense than a wired jacket / vest.

Many thanks for the superb standard of review!!"

From "P.A.":  "Aloha, I currently own the JETT heated vest that WebBikeWorld reviewed. I like it but I do have some issues with it. I think that the vest is too long going down past my belt which makes getting to belt mounted items difficult. Also the zipper is on the left side, Aussie thing maybe. These minor issues aside, it was worth the investment.

I did come across this Carbon Fiber Heated Vest while shopping for gifts and thought that it might be of interest to review as it is also wireless.
Keep them great reviews coming!"

Super Tenere Review 2012

Date: Friday 21st September 2012


One of the things about having a passion for riding motorcycles, Super Tenere or not, is that it's preferable to ride for as much of the year as possible. That requires taking heat and cold in your stride. For me, factoring in the impact of temperatures to the sport of long distance riding it becomes clear that controlling the effects of the environment are a critical part of managing fatigue and "self".

In June this year I rode from Newcastle to Darwin via Port Augusta in less than 60 hours. While riding through Coober Pedy about 9.30am despite two layers of thermals, a middle layer under my riding suit, two pairs of socks, BMW Pro Winter 2 gloves, a beanie under the helmet and a neck warmer I was so cold I was shaking too much to enter my PIN number into the EFTPOS machine while buying fuel. I can't recall ever being that cold and thinking that there had to be a better way. While looking for one, and after a throw away comment on a forum by one OX-34, I found the Jett Heated Vest on the interwebs. And guess what, it's Australian!!!

The vest operates using rechargeable lithuim batteries and comes with a battery, a charger and some almost chinglish instructions. @ $149 for the set or $195 with a spare battery. I bought the latter. I'm 195cm tall, 90kg and bought the large size. It arrived quickly after ordering online, well done Jett, and it was in tact.

You can see from the photo below it's got a couple of pockets in the front and a fairly low V neck. There's an elastic draw string on the bottom of it for adjustment and another under the arm area on the inside as well so you can keep it snug.

The Jett Heated Vest is not a fashion item, my wife (who is) wasn't very flattering when she saw it on me. I also have to say I was a little sceptical when I opened it, while it looks better on the model on the website than on me the fit was right and the battery and controller were kept at bay in a velcro pocket on the lower left front of the vest (on the inside). I wasn't sure whether it would get in the way while sitting on the bike but I guessed I'd find out.

The battery is shown in the internal pocket below. Pop it out, unplug it and charge it up. Easy. The controller has two buttons, on and off. But read the instructions, it's not perfectly intuitive.

OK, with it all charged up I got to test it recently when I rode my Super Tenere to South Australia on its first Iron Butt ride. I had it on over one layer of thermals and a long sleeve (thin) Katmandu Dri Motion top. Over the vest was my KLIM Latitude Jacket. It was a mild night at Newcastle but I was heading to the Southern Highlands in the dark. By the time I got to Marulan for fuel (about 4am) it was cold (about 4ºC not factoring in the wind chill of travelling at 110kph). I was relying on the vest working because taking layers off and putting more on in those temps is a sure way to get a chill that won't go away for the rest of the day.

So at Marulan it was time to bite the bullet and try out the Jett Heated Vest. Sadly I'd forgotten the instructions so I had no idea which of the three settings were Lo Med or High, I went with the red, which turned out to be High, but I didn't quite work that out until I was on my way. The infra red heating elements is in the back of the vest. Theres one about 10cm square positions about the cnetre o the shoulder blades and a second the same size over the lower back. One of the things that tend to happen to me when 'm riding really cold is that my shoulders and neck tense up and as a result I get sore between the shoulder blades, traps and neck. The warmth from the vest prevented that completely and I remained relaxed. The High setting was a little too toasty but not enough to encourage me to stop and turn it down.

After about 2 hours (somewhere aroung Wagga) the heat stopped, but by then the sun was up and on my back anyway. I have to say I was really, really impressed. I didn't need to turn it on again during that day's ride, but in itself, as a lightly quilted well fitting non natural material vest just wearing it provided a nice level of comfort and warmth by itself. It was a cold and very windy day.

The next time I wore the Jett Heated Vest was on the Super Tenere on the way back from South Australia 2 days later. This time I had a cotton long sleeved top over the thermals and Dri Motion top. I'd worked out that the green setting was low and leaving Wilmington South Australia about 5am heading towards Yunta was pretty cool. The low setting struggled to get heat through three layers but it was just noticeable. If I'd have been any cooler I'd have adjusted it to medium, but I didn't need to. In any case I certainly didn't feel let down by it and I turned it on again that evening while riding through Dunnedoo and Merriwa in the dark.

The battery pack didn't get in the way. At one point I noticed the controller hanging from the bottom of my jacket, there was no rain about so I didn't bother trying to secure it back inside.

Summary: I'm really impressed with the Jett Heated vest's performance, it's a great price and it's now a permanent part of my winter riding attire. My previous vest was a plain arctic fleece vest, which while good enough for reasonbly cold weather isn't any warmer than the Jett Vest when turned off and certainly can't compare when the Jett is "fired up". In fact even off the Jett vest was a little more windproof.


Wayne McDonald Business Coach 2014

"I just completed a trip through southern NSW and Victoria on my BMW motorcycle. I knew it'd be cool in a few spots but I had no idea!! I left Hamilton Victoria at 6.20am one morning and it was 2 degrees and I thought It would warm up as the sun came up. Wrong! For nearly 3 hours it hovered between +2 degrees and minus 1. For those of you that ride, you know that these temperatures on a bike are *** cold. I have heated seats and heated grips and these helped. But without a doubt the thing that made the biggest difference was my brand new Jett heated vest. To be honest I hesitated about buying it because I was sceptical – I have been riding without one for a lot of years. I am now a convert – I love this thing! All I can say was I was amazed at how warm it kept me and most of the time I only had it on the lowest setting. These vests work. If you ride during winter, you have to invest in one! Thanks Jett for a great product"
