Way too small for an adult man’s head. It looked like a beanie with a brim. All it was missing was the propeller. Wonderful technology like all Graphene-X products but if you’re an average sized man don’t bother with this until they make a larger size. I gave my hat to my wife who is a 5’6” / 130# cyclist and it fits her head fine.

Smaller than expected
The hat was too small for my head but my friend enjoys it. Everything it described works just the size for me.
