In today's world, the demand for Personal Protective Equipment (PPE) is growing, and bulletproof vests (also commonly called Ballistic Vests) are among the most well-known and crucial pieces. They aren't truly "bulletproof," but rather absorb and disperse the energy of bullets or fragments to mitigate or prevent penetration, protecting the wearer's vital organs.
Core Types:
Soft Body Armor: Made from woven high-performance fibers (like Kevlar, Twaron, Ultra-High-Molecular-Weight Polyethylene - UHMWPE). They are lightweight, concealable, and primarily defend against handgun rounds and fragmentation. This is the most common type, used by law enforcement, security, and civilians.
Hard Ballistic Plates: Typically made from ceramics (boron carbide, alumina), metals (steel), or polyethylene composites. They are inserted into the front and back pockets of a vest carrier, providing higher levels of protection capable of defeating high-velocity rifle rounds. However, they add significant weight and bulk.
Combined Protection Systems: Integrate a soft vest carrier platform with hard ballistic plates, offering multi-level protection and flexibility.

Key Protection Standard: NIJ Standard
The globally recognized benchmark is the NIJ Standard from the U.S. National Institute of Justice. It defines different protection levels:
NIJ Level IIA: Defends against low-power handgun rounds (e.g., .380 ACP, 9mm FMJ).
NIJ Level II: Defends against medium-power handgun rounds (e.g., 9mm FMJ, .357 Magnum JHP).
NIJ Level IIIA: Defends against high-power handgun rounds (e.g., .357 SIG FMJ, .44 Magnum JHP) and most shotgun pellets. This is the highest level achievable with soft armor alone.
NIJ Level III: Defends against high-velocity rifle rounds (e.g., 7.62mm FMJ), requiring hard plates.
NIJ Level IV: Defends against armor-piercing rifle rounds (e.g., .30-06 AP), requiring specific hard plates.
When choosing a vest, the Protection Level is the primary consideration and must align with potential threats faced.
