Our Enduro Knee Sleeves are trail tuned and offer pedal-friendly protection on the trail. Made from a moisture-wicking micro-lycra material and featuring a nylon mess rear panel, they keep the air flowing as you pedal up and earn the down. They allow full range of motion, thanks again to that high-stretch rear panel, and keep your knees safe from hard trail knocks with the removable D3O elbow inserts that deliver both protection and comfort as you ride. Moisture wicking micro-lycra sleeve with nylon mesh rear panel for increased airflow. Removable D3O knee inserts for the perfect balance of comfort and protection. Silicone grip top and bottom to hold the guard in place. Nylon, spandex micro lycra.
