Abstract: An article of protective equipment for protecting a body part of a user includes a lattice structure with a plurality of struts forming three dimensional volumetric structures. The lattice structure includes a plurality of internal layers, each internal layer having at least one different physical property from the other internal layers, wherein the plurality of internal layers comprises at least one internal layer having physical properties such that the at least one internal layer is capable of compressing more than at least one other internal layer in response to an impact to the article of protective equipment.
