Kalakoa means "of many colors" and the humu certainly fits that description. Hawaii's state fish pops off this hat that you'll love to wear almost as much as trying to pronounce the humu's full name. 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.
