If you wear knee braces, you've probably suffered from the chafing associated with the strap closure systems. The guys at Asterisk have the perfect solution to that age-old problem, and the Asterisk Undersleeves are a must-have if you wear braces of any make or model. Made of vented Alpha X material, the sleeves wick away moisture and help prevent brace slippage. A low-profile quad seam at the top keeps sleeves in place, and stays folded over.  Sleeves come in S,M,L,XL,and XXL, just order them in the same size knee brace that you are currently using.
