The Troy Lee Designs Raid Knee Guards are sturdy enough to provide peace of mind on challenging trails, yet comfortable and well-ventilated for a full day of riding. These knee guards are made from vented Neoprene, with D3O® reinforcement, to protect your lower thigh, knee joint, and shin. The strategically placed grippers reinforce your leg where it is most needed, including abrasion-resistant pads at the side and over the kneecap for added protection. But the best knee guards are not just protective barriers, they are also wearable and stay in place when you need them. The Raid Knee Guard features a breathable mesh back, thoughtful padding, and an adjustable fit to keep your leg dry, snug, and protected. Additionally, a flex gusset allows your leg to straighten without resistance, and a rear compression band stimulates the muscles and encourages proper function. As a bonus, the Raid Knee Guard comes with a protective, mesh-lined bag to keep it fresh between rides.
