Made with materials and developed to withstand scuffs and scrapes with minimal wear while the X-fit design minimizes the bunching that neoprene and other protective gear materials do as the rider's joints go through a range of motion.
I didn't think that these would protect too much but trust me they do. They won't protect you from a break but they do from scratches, scrapes, rocks in your elbow and getting really banged up. It was a hot day on the trail so I took these off and what do you know I fell on some rocks. Got banged up. About 5 weeks later I had them on and fell and that's when I realized how much they helped.
