Armor is constructed by sewing together a multiplicity of plies of energy absorbing cloth made of polyaramid fibers with stitching thread of relatively lower tensile strength in a pattern such that, upon impact by a projectile, the stitching threads break at multiple locations in response to stresses from fibers stretched by the impact. The armor can be sewn together to form a blanket or vest garments, etc., for protection of persons from projectiles.
