I’ve seen reviews about sizes 7 3/4 being to small for someone that has that head size. I’m a 7 3/4 head size for sure. If they are saying it’s too small they don’t know their hat size or Lying to them selfs. It fits perfectly. If you have a bigger size then it’s not for you.
The hat is pretty dang cool. Looks better In person and I will be buying another style soon. My wife likes it so that’s all that matters !
