I really wish it did not have to come to this, ballistic backpacks for children. The cutting-edge tech includes RynoHide carbon nanotube armor:
Our ballistic backpack provides built-in ballistic protection in a backpack that weighs just ounces more than a non-armored backpack. RynoHide carbon nanotube armor is lined in the back panel of the backpack. Sewn into the rear of the pack, you can always be confident that the armor hasn’t been accidentally left at home and that you or your child are protected in case of the unthinkable.
The backpack can be quickly brought to the front as a shield or can serve as center of mass protection while fleeing the scene of the shooting.
Available in boys, girls, or teen/adult models and Level II (.357 Magnum, .45, .40, 9 mm) or Level IIIA (.44 Magnum, .357 SIG and below) protection.
Designer apparel with RynoHide material is also available, as are Centurion Tactical Vests for children (bulletproof vests.)
