This is a NIKE ACG bucket hat. It's black and lightweight, making it very easy to wear. It also has a strap, so you don't have to worry about it flying off in the wind. Compared to current models, it doesn't have any unnecessary accessories, which is another point in its favor. Purchased from Atmos and only worn once, it's practically new. The size is L/XL. Although it's labeled L/XL, the fit is equivalent to a size M, and should fit most people's head sizes. If you're unsure about the size, the chin strap will help it fit to some extent, so you can rest assured. Head circumference: 57-59cm Material: Body: 100% polyester / Lining: 100% polyester Please consider it.
