On the coldest winter rides you’re going to lose a lot of heat through your head. But with a proper winter underhelmets, you can keep your body temperature up and protect your ears.

This cap is made from a stretchy fleece material that’s anatomically fitted to give you a close, snug fit. This warm material extends down over the ears and is designed to work perfectly with all Mavic helmets. There’s even a set of silicon strips over the ear pads to grip the arms of your cycling glasses so they don’t move around when you’re on the bike. And flatlock seams made from silver reflective material help you stay visible when riding in the dark.
