Abstract
Abstract A knee or elbow protector apparatus for application to an athlete's leg or arm, comprising a flexible, relatively thin wall tube that is bidirectionally stretchable, the tube having inner and outer sides, and opposite ends and sides to be stretched when slipped onto the leg or arm to cover the knee or elbow, the tube including a first elastomeric layer and a second layer of stretchable fabric attached to and substantially covering one side of the first layer; an elastomeric foam pad located adjacent the outer side of the tube and spaced from the opposite side; and retention fabric closely covering the pad and defining a loop-shaped peripheral portion that is attached to the tube.
