This bulletproof backpack panel transforms any backpack into a bulletproof backpack. This allows you the freedom to choose any backpack or to make your current backpack into a bulletproof backpack. This bulletproof panel will fit almost anywhere so you can use it in a briefcase, laptop bag, or shooter's bag. This versatile bulletproof panel uses the same ballistic materials as our bulletproof vest. Place it inside a backpack, briefcase, bug-out bag or even a purse. It provides NIJ level IIIA protection, which means it will stop almost all handgun rounds including a .44 Magnum.
