Byrna Shield

As easy to insert into a standard-sized student backpack as a school notebook, Byrna Shield Backpack Body Armor is a thin, lightweight (14 oz.), flexible Level IIIA-rated ballistic plate. It can withstand up to 6 hits from .44 magnum bullets with velocities up to 1,464 feet-per-second. This shield is 10x12, so it will fit in the laptop pocket of most standard youth and adult backpacks.
