Focus your energy on powering the pedals while SKINS cycle essentials leg warmers keep you warm. The nylon hollow core thermal fabric has a thermal rating over 200% higher than SKINS non-thermal products, & a soft feel against your skin. Silicone dot grippers prevent the warmers from slipping. A highly practical zipper at the ankle means you can put them on & whip them off without removing bike shoes or cleats. Other features include reflective logos for extra visibility, temperature & moisture management, permanent antimicrobial treatment & 50+ UV protection.
