i am slightly interested so i check to see how the whole sizing chart works out, if its like a hat (7 & 3/8th's or whatever) and i see this...
How to Measure: For best results, take measurements over your underwear. Head: Measure around your head, directly above your eyebrows.
it just gave me an image of some dude with underwear on his head and measuring for a helmet.
i dunno i have a dumb sense of humor
