One of the main features of this pack is its ability to save your life. We have sized one interior pocket to securely place a 9" x 11" ballistic plate. This bullet resistant plate combined with the arm sleeve on the back panel, can be used as a shield when weapons are being fired indiscriminately in crowded night clubs or at schools. "Place your arm in the sleeve and put the pack between you and the aggressor, this will allow you to return fire from a secured position" (ceramic plate not included). Measures 10"L x 14"W x 19"H. Weighs 3.02 lbs.
