Soft, lightweight garments that are comfortable to wear and good for the environment. Made from 31% recycled polyester and 69% bamboo fibers, the fabric feels like cotton and works naturally to wick moisture from your skin. Bamboo is a highly renewable resource, requires no pesticides to grow or chlorine to process, plus it’s naturally antimicrobial and hypoallergenic. Absorbs and evaporates perspiration more effectively than all-synthetic materials and efficiently keeps you warm in the winter and cooler in the summer. Ideal layering wear for a ride in any weather. Warning: Use caution wearing these comfy thermals anywhere close to the habitat of a hungry Giant Panda bear…mmmm, tasty bamboo. Black.
