These are genuine US military surplus Elbow Pads (a set of 2) in Multicam / OCP camo. They are designed for the arm to slip through the sleeve of the pads, and then secure in place with the two elastic Velcro straps.
These elbow pads are made by various manufacturers and military contractors, and may vary slightly in appearance.
These elbow pads have been previously used and issued by the US military, and are in very good condition. They will show minor signs of typical use including some dirt and scratches.
