Abstract: A body part protector assembly for being custom-fitted to a body part, and including a body part protector having at least two connected-together pad segments. Each of the pad segments having an initially flexible protective layer comprised of a fabric impregnated with a moisture-curable resin which hardens upon curing to form a rigid structure which retains a body part-defined shape into which it is molded during curing. Respective removable covers separately cover and enclose each of the at least two connected pad segments, and are individually removable from their respective pad segments to expose the initially flexible protective layer of that pad segment when the body part protector is to be wetted and fitted to the body part for curing into the proper molded shape.
