The KEIS B501W Ladies Heated Bodywarmer is a tailored, sleeveless thermal mid-layer crafted for women riders. Featuring elastic side panels for a flattering fit, it delivers warmth via Micro Carbon Fibre panels across the chest, back, and heated collar using Far Infrared technology. Dual-powered by your bike or a KEIS battery pack, it also enables connection to gloves, trousers, and insoles as a central power hub.
After years of layering up in cold weather and giving the lads stick for wearing heated gear I’ve joined them. My only regret is not having done so a lot earlier in life.
Arthritis makes me prone to pain on cold rides, this jacked is warm even when unplugged, but comes with three heat settings. I also bought the G701 heated gloves which are superb and again three heat settings
Jacket comes with wiring for 12v battery hook up and a FOC controller attached to the jacket.
Great value at £200 jackets £190 gloves
Note- no more layers just a Zerofit long sleeve theremal and the Keis as a mid layer and riding jacket over

Battery Run Times
12v 5000mAh Battery Pack
This calculation is based on an average run time on medium heat. Battery condition, environment, storage and usage all take effect on this run time so it is used for guidance of garment performance only and is not a guarantee.
Very happy with the fit and quality. Needs front pockets if it is to be used off the bike. Bit strange that the temperature controller was not included with the jacket (Had to pop out to the Sportsbike shop in Harlow to get one....An additional £38.00 + petrol .....On a bloody crapola day.) I would have thought that this should not be an optional extra, but included.
Having said that my partner is very happy and is looking forward to being snug and warm both on and off the bike.

Amazing
The best gift I ever received. Got it for riding in winter but I wear it all the time, on walks, gardening, sometimes just when I’m waiting for the heating to kick in. 10/10, I recommend to everyone and insist they try it on to feel how great it is.
So happy that you are getting so much benefit from your heated bodywarmer. Enjoy
Why Wear Heated Gear
If you're an all-weather rider, you'll know that the winter months can mostly be unpleasant to ride through. Especially in the UK.
Increased Control:
When your hands are cold, you lose dexterity which can make bike handling difficult. Heated gloves help minimise loss of control
Increased Comfort:
Simply put, being cold is uncomfortable. Heated kit helps make your winter rides that extra bit more enjoyable
Reduced Risk:
Being cold increases your risk of road accidents, as your reaction time and concentration decreases. Being warm on the bike equates to added protection
Flexibility:
Ride without the bulk! Heating gear eliminates the need to wear multiple heavy layers, which can prove uncomfortable when on the bike for longer periods of time
