A patent has been issued for a three-dimensional protective pad being constructed as a laminate structure that includes a top layer of a neoprene with a nylon skin attached. The top layer is stretchable in all directions and a second layer of a non-stretch neoprene-ethylene-propylene-terpolymer and a styrene butadiene rubber combination is attached under the first layer. A third layer is made of a viscoelastic polyurethane foam and attached underneath it is a fourth layer bottom layer of neoprene that has a nylon skin attached. This skin is stretchable in all directions, including a hardened polyethylene plate removably attached to an upper surface of the top layer.
