For whatever reason, scabby elbows are easier to deal with than scabby knees. That noted, it is easier not to deal with blood and bruises at all. The 661 2x4 Elbow Guard makes arm protection as easy as pulling on gloves, and nearly as comfortable. Covering each arm from the wrist past the elbow certainly won’t be as cool as no protection, but 661 puts its nylon plates and 12mm EVA padding in just the right places with plenty of Coolmax lining to wick the sweat and wide open mesh to ventilate. Sizes S, M, L and XL.
