A roomy and durable carry on gear bag constructed of rugged nylon and armored by BulletBlocker’s integrated NIJ IIIA Kevlar panel which is designed to stop threats up to .357 and .44 Magnum, 9mm, .45, hollow point ammunition, and shotgun blasts. The anti-ballistic panel is semi-rigid and non-metal, making it metal detector and airline friendly. The panel measures approximately 12 x 17″ and adds only 20 oz to the total bag weight. There are no tags or labels indicating the product is bulletproof and its size dimensions fit within standard TSA regulations. The U shaped zippered main compartment is large enough to store laptops, lots of clothing, or other items compartmentalized in the interior mesh pockets through the front zippered pocket. Several smaller compartments make it easier to organize your items. An adjustable shoulder strap with an anti-slip pad is included. The dimensions of the bag are 19.5″l x 12″h x 9″w and it weighs 2.5 lbs.
