This is an Under Armour hat with the USA logo. I purchased it in the United States, so it's likely difficult to find in Japan. The size is listed as women's, but I think it can be worn unisex. I've used it a few times. There are some minor stains on the top, the adjustment strap in the back, and the left side. Please understand that this is a used item before purchasing. I plan to fold it compactly for shipping. Thank you very much.
