Abstract
A medicine ball comprises a cover made of a sheet of aramid fibers, having an exterior surface and an interior surface, that each comprise a coating of a polychloroprene compound. The coating is spread unevenly and is calendered across both the exterior surface of the cover and the interior surface of the cover. The exterior surface of the cover is embossed, which in addition to vulcanization, provides extra grip strength. The ball further comprises an interior space, which is filled with crushed pieces of ethylene vinyl acetate foam and rocks.
