What Do Bulletproof Vests Do?

Bulletproof vests are designed to absorb the energy of a bullet, preventing it from piercing or penetrating the wearer's body. These vests are made of ballistic (bullet resistant) materials such as Kevlar, steel, polyethylene, or ceramic.

They're used by military personnel, law enforcement officers, and security personnel. A good bulletproof vest will protect you against most lead bullets and full metal jacketed bullets, and may even stop a rifle round if the shooter is close enough.

They stop bullets

A bulletproof vest is designed to stop a number of different types of gun rounds from penetrating through to your body with MICH Bulletproof Helmet. They do this by absorbing energy and dissipating it across the panel. This helps reduce the impact to safe levels, minimizing trauma to the wearer.

When a bullet strikes a bulletproof vest, the impact will flatten and mushroom against it, causing a bulge on the inside of the vest panel. This effect is called back face deformation (BFD).

As a result, it will disperse the bullet’s energy across the whole panel and slow down its forward movement. It will also stop it before it can penetrate your body and cause serious injury or even death.

However, some kinds of bullets can still get through the fabric, which can be extremely dangerous. For example, a large handgun round can travel very quickly and penetrate your vest, potentially killing you.

They absorb energy

The main purpose of a bulletproof vest is to absorb the energy of a bullet. This is achieved by using layers of extremely strong fibers that can deform a bullet as it travels through them.

In addition, they also use a material in ballistic helmets that can dissipate the energy of the bullet. This is achieved by stitching together many layers of Kevlar, a fabric that is five times stronger than steel on an equal weight basis.

It is a common material used in body armor and other protective clothing. It is a high-strength fabric that is woven from synthetic fibres.

Kevlar-based composites have been used in bulletproof vests since the 1970s. Other materials such as DSM's Dyneema and Honeywell's GoldFlex and Spectra, Teijin Twaron's Twaron, Pinnacle Armor's Dragon Skin and Toyobo's Zylon are also used in the making of bulletproof vests.

They reduce trauma

Despite stopping bullets, a bulletproof vest can still transfer some energy to the wearer. This energy can cause bruising or more serious internal injuries, depending on how powerful the impact was.

Fortunately, our Kevlar(r) vests disperse this impact across the panel, minimizing it to safe levels and preventing injury.

A bulletproof vest that's made of 16 layers will stop regular handgun and submachine-gun bullets; those with 24 layers are designed to stop the more powerful magnums from the same weapons.

These vests are also made of water resistant materials like DSM Dyneema or Honeywell SpectraShield, which are designed to be more comfortable than Kevlar and are less likely to tear in harsh weather conditions.

Most cops use a back pocket sewn into their carrier to hold trauma pads, which lessen the bruising that occurs when you get shot. But, too often officers put their backup gun holster or cell phone in that pocket and forget to grab their trauma pad!

They are comfortable

When it comes to wearing a vest such as bulletproof vests for long periods of time, comfort is essential. Make sure to find a model that feels comfortable to you. You can do this by comparing your measurements against the body armor manufacturer's sizing guide.

It is also important to buy a bulletproof vest that provides full coverage on your sides and front. This will reduce trauma if a bullet hits you in the area where it won't be covered by armor.

If you're a woman, it is especially important to get a vest that is made specifically for women. These should have real bra style cups for added trauma security.

When it comes to cleaning your vest, be careful not to use harsh chemicals. They can damage the ballistic panels, and they may cause the material to break down prematurely.
