I'm 6ft tall 190lbs, and I've been accused of having a "large" head. The hat fits somewhat more snug than I would like, but otherwise it's comfortable.

I'm giving the product a 3-star review due to the logo being 45 degrees offset from the center of the hat, while the picture shows the logo dead center over the brim. This makes me think it may have been a manufacturer defect being sold off under the official brand at the same price.
