They do actually work in keeping the sweat out or your eyes. Be prepared to take a teasing. Some people wouldn't be caught dead with one and others like them. Your choice.

I think this whole thing started with Marco Pantani. Of course he shaved his head at the time and probably needed to protect his baldness from the sun. I also heard that when you are totally bald since there isn't any hair to absorb the sweat then it it a river of it down your face. Makes sense.

BTW I think Marco has let his hair grow (it's black - hey he's Italian). Saw a photo a few days ago in regards to the Giro d'Italia race.
