The Stage Knee guard offers mid-range trail protection in a packable package. D3O® is used for impact protection. D3O® is soft and flexible to keep the guards comfortable while riding, but on impact, the D3O® material hardens to disperse the energy for protection. Slip on a pair and head out to the bike park in confidence. D3O® lightweight, low-profile elbow impact protection. Silicone grippers prevent slipping. Spacer-prene sleeve combined with breathable mesh panel for all day riding comfort. Durable, abrasion-resistant elbow panel. Sold in pairs - left / right. CE EN1621-1 Certified.
