Great for: crossfit, mountain biking and trail running. New features: impact resistive 5mm neoprene fronts fused to a compression lycra sleeve. Back zip makes them easy to get on. Foot stirrup and silicon grips keep them in place. Cleans, rope climbs, rock, and roots can be hard on your shins (so hard some athletes develop staph infections.) protect your shins with our specially designed Rock Guards.
