The ProForce Lightning Bodyguard chest gear / hogu is designed to be lightweight and flexible. The vinyl dipped foam construction allows the chest guard to move with your body providing a greater range of motion that the other body guards are not capable of. 3/4" thick vinyl covered foam offers protection over entire chest, sternum, top of shoulder, and kidney area. Uniquely sectioned to allow for a snug fit while not losing any mobility. Connect with one strap across lower back and two smaller straps at middle of back.
