Leatt's 3DF pads are light, comfortable, and easy to ride in, and that was before Leatt tacked on some extra arm protection and named it the 3DF Hybrid Elbow Guards. This sleeve has the same flexible 3DF pad on the elbow, but rocks an additional 3DF Hard Shell below, for extra forearm protection without annoying bulk or the need for a second pad. The sleeve itself is made of wicking and breathable MoistureCool fabric, so you won't sweat yourself stupid, and it's laminated with silicone to keep it locked in place while you're pedaling hard and ripping your favorite downhill track.
