The POCito Joint VPD Air Protector provides knee protection for children as they develop their riding skills in more testing terrain. Designed to stay with your child as they grow, the pads will fit over elbows if they no longer fit over the knees. Featuring the POC patented VPD Air material for protection, the exceptionally lightweight and well-ventilated protector has a barely-there feel that ensures your child won?t get too hot or uncomfortable while out riding trails. The material moves with easily with the body for ultimate freedom of movement. The protector is encased in a soft stretch fabric to ensure the pads are comfortable against the skin, and reinforced material on the outer won?t tear even after years of repeated falls. Antislip neoprene patches help keep the protectors in place, and hook-and-loop-fastenings can be effortlessly operated by children, so it?s always easy to get the children?s body armor on and off.
