Malama Pono is an island goodbye-phrase that means "take care" and it's a fitting name for this hat. First, because the honu is an aumakua, our guardian spirit, believed to take care of islanders. And, second because by blocking the sun and the elements this hat will take care of you. 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.
