The bulletproof vest, also called a ballistic vest or bullet-resistant vest, is a personal armour that helps to stop penetration of firearm-fired projectiles into the body and absorb the impact. It is worn on the torso. Soft vests are made of many layers of woven or laminated fibres and can protect the wearer from shotgun projectiles, small-calibre handguns and small fragments from explosives like hand grenades. These vests often have a ballistic plate made of metal or ceramic inserted into the vest, providing additional protection against rifle rounds, and metallic components or tightly woven fibre layers can give soft armour resistance to stab and slash attacks from knives and similar close-quarter weapons.
