We have a limited supply of Genuine Under Armour Backpacks that we are combining with our Bulletproof Backpack Inserts. Don't you just love the concept of Under Armour---with real Bulletproof Armour? These Medium sized backpacks (Original Manufacturer Price is $39.99) are perfect for students in Middle School and High School and snugly hold our 11" X 14" round top Ballistic shield in the compartment pocket, but is about 2 inches shorter than the backpack. It will also hold our 12" X 16" Bulletproof Shield loose in the main compartment to give maximum coverage. The bulletproof shield weighs under 2 lb and can stop handgun rounds up to 44 Magnum. (I personally tested one recently with my .45 at 18 inches away and it stopped it cold.) 1 color (Gray/Black) and 2 Bulletproof Shield sizes to choose from.
