Convert your existing backpack, notebook, or book bag into a ballistic shield rated at a NIJ IIIA threat level. Level IIIA is manufactured to stop bullets up to .357 Magnum, .44 Magnum, 9mm, and .45, hollow point ammunition and shotgun blasts. Our partners at Bullet Blocker have made an affordable option to provide everyday security for your loved ones. The large panel insert is designed for larger backpacks, hiking packs, briefcases, any any application where more coverage is needed. For less than $200, your backpack or briefcase just became a life-saving device offering the same level of protection worn by police officers. Each panel is made of semi-flexible soft body armor, about 1/4″ thick and encased in a washable nylon sleeve. These panels weigh less than 21oz, so light even the smallest children won’t notice the additional weight. The panels fit discreetly inside a backpack or notebook and can be easily swapped out into other bags. They’re airport and airline friendly with no TSA restrictions or metal detector concerns. Its durability outlasts the life of most backpacks. Different size and color options are available.
