The opening notes of the Hawaii Five-0 theme song changed TV as we know it so why not use them to change up your look. Let the music and a wave of cool wash over you thanks to this rhythmic design. 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.
