Includes chin strap with cord lock on Youth size, and breakaway chinstrap for Baby and Child sizes. Made of lightweight water-resistant supplex fabric, blocks UVA and UVB rays, rated 50+ UPF (ultra violet protection factor). Cold water wash by hand, hang to dry. Choose from colors as shown.

Rating : - a must have hat for an infant..
My boy is 3 month old and we were in FL for 3 weeks and this hat was very helpful. The fabric is very thin and breathable, he didn't sweat once !
