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. This hat features a printed patch and is made with 100% cotton twill fabric. It is 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 back clasp allows for a great fit. One size fits most.
