Definition
A bulletproof vest, also known as a ballistic vest, is a piece of protective armor designed to absorb the impact of bullets and other projectiles. Made from layers of strong fibers like Kevlar, it reduces the risk of serious injury or death. Think of it as a shield you wear. Unlike a full suit of armor, it's designed to be relatively lightweight and flexible. It's commonly used by law enforcement, security personnel, and military forces. The effectiveness of a vest depends on the type of ammunition used and the vest's protective rating.
