It's important to let your old man know you think he's the best dad out there. So let him show the world you think that way with this cool hat. 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.
