http://en.wikipedia.org/wiki/Bulletproof_vest

"A ballistic vest or bullet-proof vest is an item of armor that absorbs the impact from gun-fired projectiles and explosive fragments fired at the torso. Soft vests made from layers of tightly-woven fibres protect wearers from projectiles fired from handguns, shotguns, and shrapnel from explosives such as hand grenades. When metal or ceramic plates are used with a soft vest, it can also protect wearers from shots fired from rifles. Soft vests are commonly worn by police forces, private citizens and private security guards, and hard-plate reinforced vests are mainly worn by combat soldiers in the armies of various nations as well as police armed response units.
