Great Hat!
Wore it for the first time while playing a round of golf in Arkansas. It was hot and humid. Even after sweating like crazy, the only sign of sweat on the hat was the underside of the brim. As someone who is normally a 7 5/8 or 7 3/4, the sizing on the L/XL is perfect. Love not being on the last few snaps. The silicone snap is a game changer as well. It's extremely comfortable. I've already ordered two more: 1 Black/Gold and 1 Mint.
