A multi-component ballistic package for a ballistic vest comprises a first sub-panel on the strike side of the vest having overlying plies of woven ballistic fabric, a second sub-panel behind the first sub-panel comprising overlying plies of woven ballistic fabric, a third sub-panel behind the second sub-panel comprising overlying layers of ballistic fiber-reinforced thermoplastic sheets, and the fourth sub-panel behind the third sub-panel on the body side of the vest comprising overlying layers of ballistic fiber-reinforced plastic sheets. The individual plies and layers of each of the sub-panels are secured together as separate units to form, in one embodiment of the invention, a four-component structure. The preferred woven fibers are 180 denier high molecular weight extended chain polyethylene fibers. The preferred fiber reinforced sheet material comprises unidirectional extended chain polyethylene fibers. In one embodiment Threat Level III-A NIJ certification standards are achieved with a ballistic package having an areal weight less than one pound per square foot.
