1. A helmet comprising:
an outer shell, the outer shell having an outer surface and an inner surface;
a first impact mitigation layer positioned at the inner surface of the outer shell, the first impact mitigation layer having a first stiffness;
a supplemental shell, at least a portion of the supplemental shell being coupled to the outer surface of the outer shell, the supplemental shell covering a portion of the outer surface of the outer shell and configured to flex on impact from a first position to a second position; and
a second impact mitigation layer positioned between the outer surface of the outer shell and an inner surface of the supplemental shell, at least a portion of the supplemental shell enclosing at least a portion of the second impact mitigation layer between the outer surface of the outer shell and the inner surface of the supplemental shell, the second impact mitigation layer having a second stiffness that is different from the first stiffness, wherein the at least the portion of the supplemental shell and the at least the portion of the second impact mitigation layer are configured to locally deform in response to an impact on the supplemental shell.
