These gorgeous cotton cycling caps are handmade right here in Portland by the talented Double Darn. Medium caps are about 22-1/4" to 23-1/2" Large caps are about 23-3/4" to 25" Each cap is made one at a time by hand, so sizing can vary. Pairs well with our SUPER TUFF It's Pink jersey (Women's / Men's) Washing instructions: Cotton, like most natural fibers, will lose color over time and can be faded by sweat and sun. To slow discoloration, rinse your cap in cool water after sweaty rides, this will prevent salt from building up. When your cap is ready for a wash, use cool water and a bit of mild soap. Build up a lather and work any dirty spots (like the sweat band) with your fingers. Rinse well with cool water. Wring the excess water out gently, reshape the bill and dry flat.
