The POC Joint VPD Air Knee are ultra-light knee pads developed for demanding mountain biking enthusiasts looking for comfort. VPD is a material that adjusts to the morphology of the rider thanks to the heat released by the body in action. During impact, the VPD is hardened to protect the rider on the area that receives the impact. When the VPD is not subjected to a shock, it remains flexible allowing total freedom of movement. The POC Joint VPD Air Knee provides moisture wicking and reduces irritation due to friction of the pad on the skin. The elastic strap and the non-slip neoprene allow the pad to remain perfectly put during intense use.
