Abstract
A body armor insert has a set of ballistic cloth plies made from polyethylene fibers sandwiched between first and second sets of ballistic cloth plies made from aramid fiber. The number of plies in each of the three sets of plies is a function of a level of protection to be provided. Each of the two sets of aramid plies are sewn together along a central region of the set of plies. The set of polyethylene fiber plies are not sewn together except that all three sets of plies are sewn together in a shoulder region of the body armor insert.
