The challenge to making an great pair of knee guards is to build them in such a way that they are comfortable to pedal in. After all, they canÕt protect you if theyÕre around your ankles. The Summit Knee Guards provide CE-certified protection that you can comfortably ride in all day, thanks to an innovative low-profile D3O® pad. We used lightweight 4-way stretch CORDURA® fabric on the impact zones with breathable mesh back panels for comfort. These guards are the perfect choice for trail riders who want a bit more protection, but donÕt want to slow down.
