POC's Joint VPD 2.0 DH Long Knee pads throw down full-on crash protection for riders pushing their limits and pushing the sport. They use Visco-Elastic Polymer Dough that forms to your legs and is flexible when moving, that then turns rigid upon impact. It's so tough, the 3D molded VPD 2.0 complies to motorcycle standards. Kevlar reinforced stretch fabric and dual straps keep them locked down where they belong. The plastic knee cap adds an extra layer of protection and reduces friction with the ground when crashing. The extra length helps in the event of the dreaded slipped pedal strike.
