ProShield II Armored Backpack, Level IIIA
This casual looking backpack is actually a ballistic panel, rated at level IIIA. This tier of armor is designed to stop all pistol caliber ammunition up to .44 magnum or .357 SIG. IIIA armor will stop almost any pistol calibers in other words.
This backpack has other great features besides being bulletproof against most any pistol caliber ammunition, such as great storage capability and a convenient headphone port on the strap. The shoulder straps are heavily padded, and feature a mesh pouch wide enough for smartphones. Rugged and durable construction, a heavy duty carry handle, and well organized compartments round out the features of this ballistic backpack.
