The XTAK Elbow Pads are extremely lightweight and provide superior protection and shock absorption, while remaining flexible enough to move the way the body moves. The thermal plastic urethane (TPU) shell has a unique X shape and it features Cordura nylon construction with EVA high-density foam. The CoolMax inner surface wicks away moisture, while the anti-skid neoprene patch in the center helps keep the pad secured. One size.
