Nice hat. I'm really pick about my hats and this is one of the few I've really liked. I got a medium and kind of wish I'd gotten a large but it wasn't enough to return it. Unfortunately, I did have a pretty bad allergic reaction to the elastic band on the inside. I broke out like a 14 yr old with these deep, painful, boils all across my forehead. I'm going to try washing it and see if that helps. Maybe there should be an allergen warning?
