This is the specific ruling that the Illinois governing body issued for football. Nothing has been posted on the official web site for this in basketball in writing yet. The football ruling appeared a couple of weeks into the season.
"Since sweatbands (wristbands) are not to be in excess of three inches in length above the wrist, what about the forearm bands the players are wearing with their pads? Is this type of band considered legal?
Ruling The new forearm bands are made to be worn below the bicep and above the elbow and would be legal. It would not be acceptable to have a wristband above the elbow as they are made to be worn at the wrist. (September 11, 2006)"
BTW, you can't mix the two items up. It's pretty obvious when you see them that a sweatband for the wrist is not the same as a bicep band. Bicep bands tend to only be 1/2 inch wide, if that.
