Rachael Van Dolahwrote a review of Troy Lee Designs Lopes Signature Knee Guard on July 20, 2014
Familiarity: I've used it once or twice and have initial impressions
I have purchased two pairs, one for myself and one as a gift and both fit us well. These guards are light weight, but very durable and I would say they fit true according to the sizing chart. The neoprene sleeve on each pair was a tad on the tight side to start, but stretches out with use. One nice feature that sold me on this style over others was the fact that the exterior hard shell can be removed from the interior neoprene sleeve so you do not need to take off your shoes to shed the extra bulk. When you are ready for your descent and need the extra protection you can pull the hard shell out of your pack and reattach. I have yet to have any negative feedback on this item so I do not have any to share at this time, but I do have concerns about the stitching that others have mentioned in reviews below.
