ABSTRACT:
A two-piece hard hat is disclosed which enables the hard hat to be disassembled for carrying in an ordinary brief case. The hard hat is separable along a line approximately midway along the vertical height of the hard hat into an upper crown member and a lower skirt member. The vertical heights of the individual members are approximately half of the vertical height of the completed assembly to minimize the space necessary to store the hard hat.
