I was expecting something cheap, thin, and flimsy...especially since it was just supposed to be a costume piece for Halloween. When it arrived I was suprised to see how thick it was.  I think my head may be a 7 1/3 which i thought might be average...it was extremely snug but still fit.  My boyfriend tried it on and it didn't.  It really isn't one size fits all so be careful. Overall it's true to a well made real safari hat.  From the reviews I've seen, each hat may vary.
