A ballistic vest, also known as a bulletproof vest, is a type of protective clothing designed to absorb and reduce the impact from projectiles, such as bullets. These vests are commonly used by law enforcement officers, military personnel, and security professionals to enhance their safety in dangerous situations. They are typically made from layers of strong fibers, such as Kevlar or Twaron, which can stop or slow down bullets. Ballistic vests come in various levels of protection, classified by the National Institute of Justice (NIJ) standards. Some vests are designed to protect against specific types of ammunition, while others offer broader protection. In addition to ballistic protection, many vests also include features like pockets for carrying equipment and additional armor plates for increased safety against higher-caliber threats.
