yea but its not like those guys(^^) invented it or something. a friend of mine(Snowboarder) from my school last year got his grandma to make like 20 fleece lined bandanna's and sold them for $20 each on the bus to a 4 day ski trip and he sold them all, made $400 and spent it all on booz and weed.
its safe to say he had a good time.
so yea im willing to bet lots of people have alreayd thought of this and have done this.
that being said, yes i would probably buy one but you have to convince me yours are better than other people's, lol.
Im from canada, EH.
