I bought this last spring to protect against UV rays, but it was difficult to match with my casual clothes, so I'm selling it to someone. It's been tried on only, and the chin strap is also clean. The color is moss green? (dark green). From the website: This hat uses fabric that is both waterproof and breathable to prevent stuffiness from sweating. You can use it on rainy days and sunny days. It comes with a removable chin strap, so it's also recommended for those who ride bicycles. Outer fabric: 100% nylon Inner fabric: 100% polyester * UV protection rate of 90% or more Size: 57.5cm (size can be adjusted inside), brim (center) 7.5cm 6600 yen
