Asymmetric body armor
Body armor includes a panel having a front, an opposed back, left and right sides, and a top and opposed bottom. The panel is constructed from multiple layers, including a rigid sheet of metal and a spall lining. The spall lining envelopes the rigid sheet of metal in some embodiments. In other embodiments, an adhesive sheet is applied to the rigid sheet of metal, and an aramid fiber lining is applied to the adhesive sheet. The spall lining envelopes the rigid sheet of metal, the adhesive sheet, and the aramid fiber lining.
