I do like the CW-X tights, I believe my muscles felt more "supported" when I wore them. The seams in the thighs frayed, though, and I was wearing thin Adidas lycra tights instead, which felt fine but less supportive. It could all be in my head, but it felt like my muscles were "pushing" against something in the CW-X tights. My knees also felt pretty well supported (I have the 3/4 length).

They are spendy, but nice. I would wear them skiing, but I really like the 1-piece compression suit (made locally) so I don't have to worry about tucking in and overlapping and all that
