The POC Joint VPD 2. 0 Long Knee Pads protect your knees and upper shins without restricting your range of motion and ability to pedal. The 3D-molded VPD conforms to the shape of your body and offers progressive, impact-absorption where you want it most in the event of a tumble. The knee panel is perforated to enhance ventilation, and the Kevlar-reinforced stretch fabric provides a secure fit that is built to last.
