This flexible body armor panel is a level IIIA ballistic plate that uses the same ballistic materials as our level IIIA bulletproof vest. It is sized perfectly to fit inside standard plate carriers or a backpack. The panels are 10" wide and 12" long with a shooter's cut (the corners are removed to make it easier to position your rifle). It provides NIJ level IIIA protection, which means it will stop all handgun rounds up to a .44 Magnum.
