Bontrager’s Thermal arm and knee warmers are an effective and reliable option for spring and autumn riding (or cool summer days, too). They might not do anything new or different, but they don’t need to.
The arm and knee warmers are sold separately for £24.99 and £34.99 respectively but, seeing as they’ll often be worn together and, by and large, do the same job, we’ll review them together here.
They are made from Bontrager’s Profila Thermal fabric, which has a soft, fleecy lining which is super comfortable next to the skin and as warm as you’d want when it comes to arm and knee warmers for the shoulder seasons. The thermal fabric does a good job at trapping warmth in, while also remaining breathable enough to wick away unwanted moisture.
