Although the weight of some soft armor vests is a concern, others have proven to be more durable than traditional materials. Soft armor made of synthetic fibers such as nylon or aromatic polyamide has a low density, great toughness, and excellent molding properties, making them lighter and more comfortable to wear. While many people doubt that bulletproof armor made of lightweight fibers can be effective, it should be noted that bullets develop shear or tensile force when they strike a solid object. The force is then dispersed to the surrounding area, where it will consume most of the kinetic energy.
Recent advances in material science have opened up the possibility of a “bulletproof vest,” a vest made of a soft textile that can withstand bullets from handguns and rifles. Because it would not require metal or ceramic plating, this vest would be a significant improvement over current soft body armor. However, the current soft body armor is only effective against most handgun rounds, requiring armor plates for steel-core bullets (more information).
While Level IIA protection is sufficient against most handgun rounds, it is not the best option in the case of high-velocity rifle rounds. Level IIA protection is effective against all handgun calibers up to.357 magnum. Although it does not stop bullets from level IIIA or higher, it does provide excellent protection for most casualties. The only drawback of level IIA protection is its invisibility. It may be hard to keep it concealed, but the benefits of this protective vest are far outweigh the drawbacks.
