Adidas hat for children. Size: 54-57cm. Adjustable with Velcro. The fabric is mesh. The Velcro doesn't stick very well, but it works if you press it firmly! The size tag is attached, but the thread is fraying and looks like it might come off. It seems like it's meant to be cut off anyway, so it doesn't affect the use of the hat. This is a used item, so please purchase only if you understand this.
