  • Can also be powered via the Keis Cigarette Lighter/DIN Power Supply Lead (available as an optional accessory). SPECIAL NOTE - You are unable to power this heated garment using a cigarette lighter/DIN power lead on a BMW motorcycle, due to the 5Amp limit to their DIN power socket (the jacket draws 6Amps).
  • Due to the elasticated side panels you may find you need to order the chest size smaller for a snug fit.

All items of Keis heated motorcycle clothing are supplied with a fused 12 volt lead so you can power your gloves, waist coat or jacket from your motorcycle, but we also supply battery packs to keep you warm away from your bike, or so you can avoid plugging in altogether.
We also stock Keis controllers, so you can turn the temperature down and help battery life, or set the clothing to a comfortable heat - you might get too warm!

Too many characters!

Toasty warm without the bulk. Great service from infinity
Well worth it, provided it lasts a few years. I've ditched the bulky lining of my alpine stars textile jacket and wear this next to a thin fleece shirt on y morning and evening commute. Haven't needed it on full power yet. I think this is worth the extra over the sleeveless - for me it's my arms that get cold, not my core. I've also bought a pair of trousers via eBay that plug into the jacket and they work a treat, although they need a separate controller if you want them to be adjustable too. Great service from infinity, very quick. A small problem was sorted immediately without fuss.

At last toasty motorcycling!
Bought this jacket after having tried many other mid layer solutions. Had I bought this to start with I'd be quids in. This jacket is amazing! Fit is true to size, easy to install power lead to battery and plug in to jacket. Used at in -1c tempretures on medium setting and my body felt like toast. My be physiological but the rest of my body felt warm too! If used on higher setting the jacket for me was to hot. Would thoroughly recommend.
