I was in a shoe/athletic store the other day and I was looking at the stand with headbands and wristbands. Then I ran across a package of this skinny cloth bands labled as bicept bands???? Can anyone tell me what you could use a quarter inch wide bicept band for? This things didn't seem to be be enough to use to wipe off sweat. Also, if they are up on you bicept, I can't see how they could keep sweat from running down your arm onto you hand. So what are these things for?
