Fox Enduro Knee Guard Lightweight guards with heavyweight protection The Fox Enduro Knee Guards are the ultimate slip-on knee guards that prioritize pedaling comfort while offering advanced impact protection-all in a lightweight, breathable package. The Enduro Knee Guards feature the high-tech D30(R) impact-absorbing inserts. These inserts are flexible protectors that contour to the rider's body to offer unrestricted pedaling movement, while hardening during a crash to absorb the forces from an impact. The abrasion-resistant cover makes the guards long-lasting and durable, while the moisture-wicking, breathable open mesh construction stretches with the rider and increases airflow. These guards are even EN1621-1 Level 1 Certified. The Fox Enduro Knee Guards might just be the most comfortable way to stay protected on the trails.
