A stab vest is a protective garment designed to provide resistance against stabbing or puncture attacks. It is an essential piece of equipment for law enforcement officers, security personnel, and others who may face violent attacks. Synonyms for stab vest include ballistic vest, body armor, bulletproof vest, bullet-resistant vest, and protective vest. Ballistic vests are designed to protect against bullets, whereas stab vests protect against knives and other sharp objects. Bulletproof vests may also include protection against sharp objects, but they are primarily designed to stop bullets. Whatever the terminology used, the vest's purpose remains the same - to protect the wearer from harm during potentially dangerous situations.
