Abstract
Abstract An improved chest protector including additional protection to the sternum area of an athlete's chest. The additional protection is provided by relatively rigid plates bonded to the conventional shock-absorbing chest protector material on the side opposite the wearer's body and directly over the sternum area. The plates distribute the impact from a high speed object over a relatively large area of the shock-absorbing material, thus allowing the chest protector to absorb more of the object's energy than is possible with prior chest protectors.
