It doesn't take a detective to figure out this is one cool hat. Turning the Hawaii Five-0 wave and establishing shot of Diamond Head into an original painting is a classy way to celebrate the 50th anniversary of this classic show. Featuring a printed patch, this hat is made with 100% cotton twill fabric and has an interior sweatband to wick away moisture. It's enzyme washed to be 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.
