Bulky pads have no business interfering with our ride, and Troy Lee Designs ensures the Raid Knee Guard is anything but intrusive. Flexible neoprene and mesh house tough padding to keep our knees from getting torn up by the trails, and an abrasion-resistant cover provides durability while we're swerving on singletrack. A polyurethane calf band and silicone gripper hold everything in place, and a breathable construction keeps us from overheating.
