For over 46 years it has been about protection. Protection from debris, roost, rocks, and branches. O'Neal offers the extra layer of protection a fabric jersey can not provide. When it comes to safety and function, O'Neal's full line of protection provides sizes, features, and function for every type of rider on all types of terrain. Lightweight and well ventilated knee protection. Innovative, hinged knee pivot design, moves with you rather that restricting movement. High impact-resistant, injection-molded plastic. The design ensures the protection stays in place while riding and during crashes. Pre-formed foam inner is molded to the shape of the knee for added comfort and protection. The inner knee bolt is counter-sunk to prevent damage to the bike. All rivets and bolts are covered with padding.
