I used this for golfing, and the size of the bill is perfect for me. However, because of the way the sides are shaped, it put pressure on the back of my head. So I boiled some water and held the ends in for about a minute, and was able to bend the sides out a little. I used an ov-glove to bend it, cuz it was hot. After it cooled down, it now fits perfectly, with no pain!
