Carve Knee pads offer coverage extending a little below the knee to boost protection a bit further. Front impacts are soaked up by their slow rebound X-Matter foam padding which covers the knee area, and SideTap foam on either side. The Kevlar outer cover is pretty tough and reasonably stretchy, moving with the main body of the pad, so your own movement is not restricted. All this protection is sewn onto a moisture-wicking Aeromesh body to keep you cool. The entire pad is held in place by velcro straps at the top and bottom, and an internal silicone print.
