This is a gorgeous one of a kind hat. It’s original NFL Super Bowl merchandise hat brand new with tags. Please take a close look at the many pictures of the hat and the sizing info. The details and quality of the hat is worthy of the original $175 price tag. The size says Large but it is not too big. Seem regular one size to me. Not familiar with NFL sizing. I measured my head around forehead and I am aprox 23" max. The hat fits me a tiny little bit tight.
