Abstract
A custom-fitted helmet in which a preformed elastomer sack containing a resin-bead composite adapted to rigidify in response to mechanical deformation accommodates a single rigid outer shell to various individual head sizes. The underside of the sack is formed with circular channels concentric about the top of wearer's head which lockingly receive resilient strips that are part of a preformed inner helmet assembly. The resilient strips are carried on the inner assembly by intermediary energy-absorbing strips which are in turn adhered to a flexible leather liner fitting over the wearer's head.
