The P1 is Aero's senior forearm protector: a thin layer of high-impact plastic sandwiched between EVA 30 and EVA 70 foams, then 3D moulded so it sits snug on the arm and stays out of the way of the shot. The stretch-fit sleeve does away with straps, so there is nothing to restrict circulation, and the moisture-wicking closed-cell construction is machine washable. Ambidextrous. Small 23-25 cm, Medium 26-27 cm, Large 28-30 cm, measured elbow to wrist.Specifications Coverage: Forearm, elbow to wrist; ambidextrous sleeve Material: Thin layer of high-impact plastic sandwiched with EVA 30 and EVA 70 foams, 3D moulded; moisture-wicking, closed-cell foam, machine washable Straps: Stretch-fit sleeve with durable elastic ends; no straps Sizes: Small (23-25 cm), Medium (26-27 cm), Large (28-30 cm), measured from the tip of the elbow to the wrist
