The Summer Sun Hat ties in two places to secure it for active summer wear. First, the hat band ties in the back to help with size adjustment and keeping the hat in place. Second, the chin straps keeps this wide brimmed hat on your head in the wind. The chin straps cannot be seen in this animation; they are tied behind the head, out of sight. 100% cotton, the Summer Sun Hat is washable and can be rolled, for safe storage in a pocket.
