A ballistic vest or bullet-resistant vest, often called a bulletproof vest, is an item of personal armor that helps absorb the impact and reduce or stop penetration to the body from firearm-fired projectiles- and shrapnel from explosions, and is worn on the torso.
A firearm is a portable gun - a barreled weapon that launches one or more projectiles, often driven by the action of an explosive force.
Body armor or Body armour, or personal armoror deflect slashing, bludgeoning and penetrating attacks by weapons.
A projectile is any object thrown into space by the exertion of a force.
What's inside a Bulletproof Vest? by What's Inside?
Soft vests are made of many layers of woven or laminated fibers and can protect the wearer from small-caliber handgun and shotgun projectiles, and small fragments from explosives such as hand grenades.
A shotgun is a firearm that is usually designed to be fired from the shoulder, which uses the energy of a fixed shell to fire a number of small spherical pellets called shot, or a solid projectile called a slug.

These vests often have a ballistic plate inserted into the vest.
Metal or ceramic plates can be used with a soft vest, providing additional protection against rifle rounds, and metallic components or tightly woven fiber layers can give soft armour resistance to stab and slash attacks from knives and similar close-quarter weapons.
A rifle is a firearm designed to be fired from the shoulder, with a barrel that has a helical groove or pattern of grooves cut into the barrel walls.
A trauma plate, also known as a trauma pack, is a plate that is an add-on component/insert to a ballistic vest.
Soft vests are commonly worn by police forces, private citizens who are at risk of being shot, security guards, and bodyguards, whereas hard-plate reinforced vests are mainly worn by combat soldiers, police tactical units, and hostage rescue teams.
A bodyguard is a type of security guard or government law enforcement officer or soldier who protects a person or people — usually high-ranking public officials or officers, wealthy people, and celebrities — from danger: generally theft, assault, kidnapping, assassination, harassment, loss of confidential information, threats, or other criminal offences.
A security guard, security officer, or protective agent is a private person who is hired to protect an organization's assets from a variety of hazards by using preventative measures.
Body armor may combine a ballistic vest with other items of protective clothing, such as a combat helmet.
A combat helmet or battle helmet is a type of helmet, a piece of personal armor designed specifically to protect the head during combat.
Vests intended for police and military use may also include ballistic shoulder and side protection armor components, and bomb disposal officers wear heavy armor and helmets with face visors and spine protection.
Bomb disposal is the process by which hazardous explosive devices are rendered safe.
Ballistic vests use layers of very strong fibers to "catch" and deform a bullet, mushrooming it into a dish shape, and spreading its force over a larger portion of the vest fiber.
The vest absorbs the energy from the deforming bullet, bringing it to a stop before it can completely penetrate the textile matrix.
Some layers may be penetrated but as the bullet deforms, the energy is absorbed by a larger and larger fiber area.
While a vest can prevent bullet penetration, the vest and wearer still absorb the bullet's impulse.
Even without penetration, heavy bullets deal enough force to cause blunt force trauma under the impact point.
Vest specifications will typically include both penetration resistance requirements and limits on the amount of impact force that is delivered to the body.
Vests designed for bullets offer little protection against blows from sharp implements, such as knives, arrows or ice picks, or from bullets manufactured of non-deformable materials, e.g., those containing a steel core instead of lead.
Steel is an alloy of iron and other elements, primarily carbon, that is widely used in construction and other applications because of its high tensile strength and low cost.
An ice pick is a tool used to break up, pick at, or chip at ice.
This is because the impact force of these objects stays concentrated in a relatively small area, allowing them to puncture the fiber layers of most bullet-resistant fabrics.
By contrast, stab vests provide better protection against sharp implements, but are generally less effective against bullets.
A stab vest, or stab proof vest is a reinforced piece of body armor, worn under or over other items of clothing, which is designed to resist knife attacks to the chest, back and sides.
Textile vests may be augmented with metal, ceramic or polyethylene plates that provide extra protection to vital areas.
These hard armor plates have proven effective against all handgun bullets and a range of rifles.
These upgraded ballistic vests have become standard in military use, as soft body armor vests are ineffective against military rifle rounds.
Prison guards and police often wear vests which are designed specifically against bladed weapons and sharp objects.
