This is a Montbell reversible Bird Bill Cap. It's reversible, with gray and navy colors, and the size is L. I bought it intending to use it for cycling, but I never used it and just stored it. This cap has a high-fitting design that makes it easy to wear under a helmet or hood. The shape of the brim can be adjusted freely. It uses soft fabric, and you can enjoy different looks on the front and back. Specifications: Material: 70-denier full dull spun-like nylon tasser Average weight: 27g Brim length: 7.0cm Features: UV cut / Reversible
