Protective gear such as a helmet includes multiple shell layers connected through energy and impact transformer layers. The energy and impact transformer layers may include conical structures used to dissipate mechanical energy applied to an outer shell layer while allowing an outer shell layer the ability to rotate with respect to a middle or inner shell layer. The conical structures may be three dimensional pyramids, three dimensional parabolic structures, and may be outwardly or inwardly oriented.
