Be sure about your size. I measured according to the size chart and ordered as suggested a medium. It was loose and slipped down as soon as I put it on. I exchanged it for a small and the fit was fine. I only have one full day use with them so far and can't comment further.
These are great for any brand knee brace because of the length. I also have some thor brace sleeves and they are not nearly as long. It generally is not a problem but have the sleeves up higher on your thigh prevents them from slipping down and causing the brace to contact directly on your skin.
