I've bought 4 of these hats. 2 brown, black and grey.1) Of those the black was a lot smaller than the brown and the grey. Granted I have a big head but there is a noticable difference in size.2) my cap/button on the top came off of one of my brown hats so I bought another. The new one was the same size as the black one I bought a few months before. A lot smaller than the old one.
