What does an NIJ rating mean?
NIJ stands for National Institute of Justice, the governing body that oversees performance standards and testing for ballistic armor. NIJ is the standard by which all commercially available body armor is judged for safety and ballistic stopping power. Not all ballistic armor is created equal.

What does NIJ level IIIA mean?
According to the National Institute of Justice (NIJ), Level/Type IIIA body armor is designed to defeat a . 357 Sig FMJ Flat Nose (FN) weighing less than 8.1 grams or 125 grain. The muzzle velocity must be under 1,470 ft/per second at this weight for a Level IIIA to stop the bullet.
What is the highest level of ballistic protection?
level IV
The highest level of the NIJ ratings, level IV, can withstand the impact of up to a . 30 armor-piercing rifle. Level IV armor is most ballistic protection offered in current day, and is what is issued to soldiers in the military.
