ABSTRACT:
A helmet includes an outer shell and an inner liner. The inner liner includes a visual indicator to indicate when the helmet has experienced an impact of sufficient force to permanently deform a portion of the inner liner. The visual indicator thus indicates when the helmet no longer offers it's peak level of protection to the wearer and should be repaired or replaced.
