Good protection, Very uncomfortable
They do fit nicely under my MX pants, and also a good tight mold against my knee and shins. But the straps are very uncomfortable. The top strap always slides down the thigh to the knee awkwardly, and the knee bend in these are OK. They might be better with a spandex under armor, but I wouldnt recommend these. Im exchanging and hoping to find something more comfortable.

PROS: Good Protection, Stylish, Tough

CONS: Uncomfortable, Straps Chafe
