1. An article of protective equipment for protecting a body part of a user, the article of protective equipment comprising:
an innermost surface positioned closest to the body part of the user when the article of protective equipment is worn; and
a lattice structure comprising a plurality of struts forming volumetric structures, the lattice structure comprising:
a plurality of internal lattice layers, each internal lattice layer having at least one different property,
wherein the plurality of internal lattice layers comprises at least one internal lattice layer comprising a first set of struts, each strut of the first set of struts having a first diameter such that the at least one internal lattice layer is capable of compressing more than at least one other internal lattice layer in response to an impact to the article of protective equipment,
wherein the at least one other internal lattice layer comprises a second set of struts, each strut of the second set of struts having a second diameter that is different than the first diameter, and
wherein one of the at least one internal lattice layer or the at least one other internal lattice layer is positioned closer to the innermost surface than the other of the at least one internal lattice layer or the at least one other internal lattice layer.
