Great hat. I was skeptical it would fit because 90% do not. Large head; old school hat size 7-3/4 to 7-7/8. Perfect loose comfy fit on two clicks, "wouldn't blow off in the wind" tight on three clicks. Love the old style design, size of cap, type of mesh, curve of the smaller bill. I'm not flattered by the new hip urban giant flat bill hats worn rakishly off to the side; just "not my jam". Make more of these. I will buy more for gifts.
