Its wide brim and UPF 50 fabric give you maximum protection while its light, cool, Teflon-treated fabric keep you cool, comfortable and dry. A built-in, adjustable, removable chin strap is nice on boats so your new hat doesn't blow off into the deep blue. A great hat for that trip to the tropics or for anywhere in summer.
