Evo Shield Upper Arm Guard - EvoShield's performance compression fabric delivers maximum breathability and support to keep your blood circulating throughout the game and promote faster muscle recovery. The lightweight Nanocell™ pads in the Upper Arm Guard are strategically placed over the forearm and triceps, contoured to fit your arm without bulk. This lends additional protection against slashes and cross checks. The sleeve is a polyester and spandex combination that wicks sweat to keep you dry. Comfortable flat-lock seams add durability without irritation.
