Layers are the key to staying warm in the saddle on chilly riding days. With a collection of unique Japanese-developed fabric technologies, Zerofit offers every base layer a rider could possibly need. The Heatrub Ultimate is a traditional base layer to seal in body heat, and the technology also creates frictional heat for extra warmth. Heatrub Move does the same but is designed for higher levels of activity. The Cold Skin layers protect you from the sun’s harmful UV rays, while the Thermoweave technology enables unconstrained body movement with 500% stretch. Rain, shine, or snow, Zerofit has the base layers to keep you cozy on the road.
