Bulletproof vests, are sometime referred to as a ballistic vest or bullet-resistant vest. It is an item of personal body armor that helps absorb the impact and reduce or stop penetration to the body from firearm-fired projectiles and shrapnel from explosions. It is usually worn only on the torso of the body. Soft vests are made of many layers of woven or laminated fibers. They can protect the wearer from small-caliber handgun and shotgun projectiles, and small fragments from explosives such as hand grenades.
