EDIKO Cap Full Mesh Color: Navy Size: Free Size This hat is made entirely of mesh material, making it very breathable. It's a golf cap, but it would also be useful for other sports and outdoor activities where you tend to sweat and get stuffy. The size can be adjusted with the belt. It can be adjusted to approximately 55-60cm, and can be worn by a wide range of people, both men and women. I bought it new online and it has been opened, but it's almost unused as I've only tried it on at home. Please refrain from purchasing if you are sensitive to items stored at home. It will be shipped in a flat envelope. *Please read the profile before asking questions or purchasing. I have a large number of hats that I have collected as a hobby, so if you are interested, please take a look at the link below. #Baton's Hat Collection EDIKO Golf golf Hat Cap Mesh Cap Cap Hat
