unfortunately I had to return it because it was too snug for comfort. I measured my noggin with a tape measure and used the size chart. The hat was simply a bit too snug for comfort. In fact, the recommended size was exactly that of a welding helmet or face shield (if any of you wear those at work), which are SUPPOSED to be snug. I suggest going one size bigger that the chart saysOtherwise, the hat is very nice quality. Four stars only because of sizing issue
