Body armor is a piece of equipment specifically designed to protect the wearer from bullets and other ballistic threats. They are typically made of multiple layers of high-strength fibers, such as Kevlar, or ceramic composites that effectively disperse and absorb the impact of a bullet. Modern body armor not only focuses on protective performance, but also takes into account comfort and mobility to ensure that the wearer can move freely in a crisis situation.
The grade and performance of body armor varies according to the threat level, ranging from protection against pistol bullets to rifle ammunition. In general, the choice of body armor should be based on actual needs and potential threats to ensure that the best protection is provided.
As technology has evolved, so has body armor, from being heavy and inflexible at first, to being lightweight, comfortable and versatile today. They have played an important role in the military, law enforcement, and personal security, becoming a core component of modern protective equipment.
