Bulletproof material commonly known as Aramid Ballistic Protective Material was first developed by engineers at DuPont. The trade name is Kevlar. In order for the material, which is made up of individual strands to prevent projectiles from passing through, a layer system is used. Typically 24-26 sheets of the material are pressed and adhered together building up to roughly 1/4 to 1/2 inch of padding. This makes the inserts ideal for backpacks and bags. When a bullet comes into contact with the material the focal point is distributed throughout the bulletproof panel allowing for the insert to absorb the impact. 

The National Institute of Justice (NIJ) has set standards for the protection level of bulletproof materials. The range from NIJ II / IIIA/ III and IV. The higher the rating the more protection is offered. Level III and IV panels are typically made from steel or ceramic. This allows for stronger protection from higher caliber ammunition. The extra strength causes an increase in weight and mobility. 

For bulletproof backpacks and cases the NIJ IIIA inserts are the most common. They weight less than 2 lbs and are semi-flexible making them ideal for packs and vests. 

When choosing the level of protection you want take into consideration the weight differentials and the mobility desired. We offer multiple shapes and sizes to fit into almost any bulletproof  backpack, case or vest. For more information visit our video links.
