Bulletproof vest, also known as a ballistic vest or a bullet-resistant vest, is an item of body armor that helps absorb the impact and reduce or stop penetration to the torso from bullets and fragments from explosions.The bulletproof vest was invented by Casimir Zeglen in 1893.

The bulletproof vest, also referred to as a ballistic vest or bullet-resistant vest, stands as a pivotal innovation in the realm of personal protection and law enforcement equipment. It serves the crucial purpose of safeguarding individuals from potential life-threatening situations by absorbing the impact and mitigating the effects of bullets and explosive fragments directed at the torso.

The invention of the bulletproof vest can be credited to Casimir Zeglen, a Polish engineer and inventor, who introduced this groundbreaking concept in 1893. Zeglen's creation marked a significant advancement in the field of personal protection, providing wearers with an added layer of defense against firearm projectiles.

The primary function of a bulletproof vest is to disperse and absorb the energy generated upon impact by a bullet. This is achieved through the implementation of various materials, such as layers of woven fibers or laminated composites, designed to deform and dissipate the force of the incoming projectile. Modern bulletproof vests are often constructed using materials like Kevlar, Twaron, Dyneema, and other high-strength synthetic fibers, which offer optimal protection while maintaining flexibility and comfort for the wearer.

Bulletproof vests are categorized based on the level of protection they provide against different types of ammunition. The National Institute of Justice (NIJ) in the United States, for instance, classifies vests into various levels, ranging from Level I to Level IV, each offering varying degrees of protection against ballistic threats.

Law enforcement officers, military personnel, and individuals in high-risk professions commonly rely on bulletproof vests as an integral component of their personal protective gear. The widespread adoption of these vests underscores their crucial role in enhancing the safety and survivability of those who face potential gunfire or explosive threats in the line of duty.

Over the years, advancements in materials and manufacturing processes have continued to improve the effectiveness and versatility of bulletproof vests, ensuring that they remain a vital tool in the realm of personal protection for those who risk their lives to maintain public safety and security.
