The Warrior Nation 11 Arm Guard offers comfort-based protection. It's built with pads in key impact zones on the exterior of the arm, allowing for maximum flexibility. One of the lightest pad series in the industry, each pad is constructed of ultra thin, dual-density foams that are hard on the exterior and soft on the interior. A slim, ABS plastic elbow cap deflects impacts away from the bones in the elbow. Sizing: M (for players 5'6"-5'10", 130-160 pounds), L (for players over 5'10", 160 pounds).
