DFNDR Armor® Level III Rifle Rated Backpack Shield inserts are independently tested to meet NIJ protocol. Our Armor is engineered with the highest grade of ballistic materials; an ultra-high molecular weight polyethylene (UHMWPE) Fiber-Lite Laminate, bound with a resin matrix, to make it a hard stand alone armor system. This armor is equipped with state a of the art Trauma Mitigation Base and Spall-Tek to further reduce spall and deflection of projectile fragments. This armor can be inserted into almost any backpack (measure your backpack, bag or purse to ensure fitment).
