I have always had a big head (size 4XL), even as a kid. I asked ChatGPT and it led me here. I have issues with light and it makes such a difference having a hat when it’s a bright sunny day. I love the hat and I’m so grateful that products like this exist. It’s a great hat. Fits well and I like how it looks on me.

I bought a 3XL for my dad who has a 25 inch head circumference and it runs a little big but not too much. With the included foam insert it fits great!

Genuine 47Brand hat. Great fit. Had to get a 3XL-4XL but didnt need it on the largest setting which was surprising. I usually wear a fitted 8⅛ / 8¼ due to my giant head. This was a great find. Will do business with them again.
