These knee guards offer maximum protection without sacrificing freedom of movement or comfort, so you can face the most challenging Downhill descents with no hesitation. Taking inspiration from natural fractals, the design of the two sliding polyethylene plates distribute the force of impact over a broad area, for minimum shock to the knee. Surface vents provide constant ventilation, making these guards ideal for wear even with long pants. Side padding bolsters protect the knee from bumps with the frame while the smooth surface creates minimal friction allowing the plates to slide easily in the event of a crash. The LYCRA® Jersey Hole sock, with its highly breathable open-back design, offers infinite adjustment possibilities for perfect adaption to all bodies through its comfortable Velcro straps and elastic grippers that protect the calf with no need for adjustment throughout the day.
