2 reviews
The KEIS B601 ULTRAFLEX Heated Bodywarmer is a lightweight sleeveless mid‑layer that helps you travel without bulk. Constructed with 4‑way‑stretch UltraFlex fabric and featuring Micro Carbon Fibre heating panels in the chest, back, and collar, it delivers effective Far Infrared warmth. Breathable and slim, it’s ideal under motorcycle jackets or touring gear. Can be powered by a bike’s 12 V lead or via a KEIS battery pack using its integrated power hub.
They seem good. Nice and thin so can use them under my regular gloves. I've got those mits for motor bloke as well. Nice that they come with connectors for bike battery. Hope they make a difference this winter
Brilliant bit of kit, I lost mine recently and immediately replaced it , that's how important this jacket is. I can wear a light summer jacket with this underneath so no bulky jackets, and with the push of a button instant heat and comfort unbelievable.
Just what you and your hands deserve, having ridden for over 45 years and suffering many a winter with ice cold hands, Keis gloves and garments are essential and not a luxury item for all year riding.
This is by far the best piece of kit I have purchased for a long long time! Last week a buddy of mine and I went on a Baltic countries adv adventure and the vest kept me warm even when the temp dropped down to 3 degrees on our way back through Finland. It's light and thin and you hardly notice it under the jacket. It heats up in seconds and the heat is evenly distributed over the whole vest. When connected to Hex Ezcan on a BMW (R1250GS) the heating levels are controlled by the button for the heated grips, so it's fully integrated into the bike's system which makes it simply brilliant!
Absolutely love this jacket...these April mornings have been down to 2 degrees a d this jacket has been the difference of me riding to work on taking the car.....brilliant....only my little fingers have been cold.....might have to get the gloves next
Excellent products, gloves jacket trousers socks and excellent customer service, had issue with gloves whilst on bike and discarded the original packaging but was still allowed to return/swap

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
