Mountain elbow guard with D30 technology that absorbs and dissipates energy on impact. This reduces the transmission of force to the body. CE-certified technology against impacts is efficient even at high or low temperatures. The outer section of the elbow is constructed of Cordura to increase durability and resistance during impacts and is reinforced with a protective plate to reduce friction in a sliding fall. The back of the arm is constructed of mesh to wick away perspiration and stay dry. D30 inserts are removable for easy cleaning.
