DFNDR Armor® Body Armor is equipped with a state-of-the-art Trauma Mitigation Base to minimize the energy of an impact dramatically. All threats specified are tested at muzzle velocity and are listed in the ‘threat profile’ table below which describes the rated ammunition this armor system will defeat. The DFNDR Armor® Level IV system incorporates a Crystalline Ceramic Strike Face and Strike Core supported by our proprietary System Structural Reinforcement technology to enhance multi-hit ability. The backing support is engineered with the highest grade of ballistic materials; an ultra-high molecular weight polyethylene (UHMWPE) fiber, bound with a resin matrix to make it a hard stand-alone armor system and equipped with Spall-Tek to further reduce deflection of projectile fragments. This system is independently tested to the NIJ 0101.04 protocol at NIJ Certified Ballistic Labs in a Stand-Alone Configuration. *Torso plates sold individually *Purchase (2) for front and back
