<p>A b allistic performance and trauma reduction system for soft body armor including a solid plastic sheet cut into multiple sections of geometric designs which overlap and are stitched to one or more layers of woven or non-woven ballistic fabric contained within a ballistic package of the soft body armor. Energy is transmitted through the ballistic sheets to the plastic sheet improving ballistic performance and reducing trauma to the wearer's body, resulting in safer, thinner and lighter armor.</p>
