Elbow and knee guards are used in sports in which the athlete must expect regular contact with the ground or floor. This guard utilizes hinged resilient members along the lateral direction of the joint and sliding slots which allow the guard to both rotate and deflect along the longitudinal direction. As the knee or elbow is flexed, the skin stretches in the longitudinal direction carrying the resilient members along and consequently the guard stretches and changes its shape to match the shape of the limb. The aluminum hinges allow the joint to flex in the lateral direction. The guard does not don the limb and thus eliminates chafing. The guard is placed over the knee or elbow. By pressing on the guard with the hands, the aluminum hinges will deform until the guard conforms to the contour of the surface.
