9 reviews
The KEIS T103RP Heated Trousers are slim, breathable under-layers designed to fit under armoured trousers without adding bulk. Using Micro Alloy-Fibre heating technology, they deliver even warmth across the thighs and knees. A controller connection flap enables the use of either standard or Bluetooth KEIS Power Controllers. Compatible with bike 12V systems, they also accept a portable KEIS battery for off-road warmth.
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
The KEIS T103 Heated Trousers are designed as a base layer to be worn under your usual armoured motorcycle trousers, delivering powerful warmth without adding extra bulk. Using Micro Alloy-Fibre heating technology, they provide lightweight, breathable Far Infrared heat across the thighs and knees for improved comfort during cold-weather rides.

Elasticated panels and a soft, moisture-wicking lining ensure a comfortable, flexible fit under outerwear. Powered via your vehicle’s 12V supply or an optional KEIS portable battery for off-bike use, they integrate seamlessly with other KEIS heated garments. Includes: T103 Heated Trousers, 12V Vehicle Supply Lead, instructions.
Even Heat Distribution via Micro Alloy-Fibre Panels
Strategically placed across thighs and knees, these lightweight softshell panels provide consistent warmth without hotspots—ideal for cold-weather riding comfort.
A dedicated flap lets you attach either the standard KEIS Power Controller or the Bluetooth version for remote heating control, offering flexibility for both on-bike and portable use.
Micro Alloy-Fibre: a heating technology that evenly distributes heat and prevents hot spots
Dual Powered: designed to integrate seamlessly with your motorcycle's 12V power system. You can also power them with a separate portable KEIS battery for use off the bike.
Water Resistant: designed to withstand the elements using waterproof and durable materials
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
