The Good: They fit, they breath, they protect, they do not move.
The Bad: did I mention they do not move :-)Overall Review: I have used these for both trail riding and lift assisted riding. I highly recommend these. The X-Strap setup magically keeps these things from moving around. I don't know why Fox does not use this technology on all their guards (buddy has a nicer more expensive looking set and he can't keep them up on his leg to save his life). My only complaint which probably is not a valid complaint is that my legs would get hot while trail riding (pedaling) but really only notice this on hot days which I think is to be expected. For lift assisted riding they are perfect. I would buy them again.
