Navy polyester hat, size 52cm, with a decorative band. - Size: 52cm - Color: Navy - Design: With decorative band - Material: 100% Polyester There's a place to attach a chin strap. The chin strap is missing. The sunshade is stowable. Because the fabric is polyester, I used it for swimming in the pool and playing in the river. I think it can still be used in the coming season. Thank you for looking.
