The iXS Slope-Series Evo knee guards provide ample protection, are comfortable enough to wear for an extended period of time and durable enough to stand up to the abuse they'll see. AeroMesh material throughout allows more air flow than other comparable materials, while the rear features an open section behind the knee joint to prevent excess fabric from bunching up. The hard knee-cup is covered with Kevlar fabric that resists ripping (when you're face down, sliding across the ground) while Hook-and-loop straps at the top and bottom, along with Silicone gripper strips help to keep them in place.
These knee guards fit extremely well!! The won't ride down with the silicon around the top or bottom. Very comfortable knee guards!!
