Abstract
Abstract The present invention relates to an improved protective chest shield particularly adapted for use in sporting events. The protective chest shield includes an elongated pad having enlarged portions at both ends. The pad includes an inner layer of closed cell polyvinyl chloride foam and an outer layer of polypropylene. The pad has a plurality of apertures extending therethrough. Each of the apertures extending through the polypropylene is beveled having the larger end spaced away from the polyvinyl chloride foam. A fabric strap extends through a pair of proposed apertures adjacent to opposite ends of the pad but adjacent to the same edge. The fabric strap extends through a second pair of apertures adjacent to the same ends and the opposite edge. The fabric strap is adapted for tying together to provide a means for holding the protective chest shield onto a wearer.
