A ballistic helmet body made up of a plurality of plies formed from flat hexagonal blanks of ballistic fabric. Before being formed to the shape of the helmet body each blank is slit along lines extending from spaced points around the periphery thereof toward the center to form a generally circular central area and a plurality of contiguous segments extending outwardly from the central area. When the blanks are formed to the shape of the helmet body, adjacent segments overlap over first portions to leave second portions which do not overlap. As successive plies are laid up they are relatively oriented so that second portions of one ply are covered by first portions of another ply.
