Though we don't know their names, the first voyagers that mapped out the Hawaiian islands are still legends to those that call this place home. We honor them and this volcanic archipelago with our classic geographic design. This hat is made with 100% cotton twill fabric and has an interior sweatband to wick away moisture. It is enzyme washed so it's soft and has a pre-formed plastic bill to look broken-in from the first day you put it on. The adjustable Flip-N-Grip Soft buckle system allows for a great fit. One size fits most.
