The VPD material adapts to your body shape but stiffens upon impact for excellent impact absorption. Joint VPD 2.0 Knee Protector. 3D Molded VPD 2.0 : Advanced knee protection that conforms to your knee's shape.
Upgraded from some smaller, but still good TLD pads that slid down during a minor crash. Decided to spend the extra money and pick these up. Well worth it. I've only had one moderate spill with them and I didn't feel a thing. They absorbed the impact and stayed in place on my leg. Good product, very happy mtbr.
I bought the larges cause I couldn’t find any that were bigger. I was on the brink of large and x large. I’m glad I had to choose the smaller ones. They are tight but that’s good. I though they might be way too tight but once I started riding I barely noticed they were there. I ride with them every ride for safety. Never know when you go down.
