Immediately after the appearance of firearms, people began to think about how to protect the body from bullet hits. Initially, heavy metal armor was used for these purposes, which, although it stopped the shot, strongly constrained movement. Now the military has body armor. They are much lighter and more comfortable, due to which they are practically not felt on the body. If you decide to  buy a br one vest , then you should focus on a number of factors.

Now on the market there are a large number of similar products for various purposes. Some are designed to be worn outside while others are hidden under clothing. There are also models with built-in pockets. A plate is used as a protective element, which is made of several types of metal.

Each country has its own classification of body armor. The standards allow you to determine the protective properties of the product, as well as the types of weapons from which it protects.

The ability to stop the bullet directly depends on the thickness and type of substance used in the manufacture. As a rule, modern body armor is made from the following materials:

  • Kevlar;
  • Polymers;
  • Ceramics with the addition of metal;

It is important to understand that when testing products, it is assessed not only whether the shot has reached the body, but also the presence of a pre-armor injury. This is due to the fact that a bullet, when it hits the surface, has tremendous kinetic force, which can leave a serious wound even if it does not touch the surface of the body. To assess the injury received during testing, a special material is used that mimics the human body. When hit by a bullet, the depth of the dent should not exceed four centimeters.

The most popular substance used in the manufacture of body armor is Kevlar. For the first time this material was developed almost 50 years ago, and its strength properties significantly exceed steel ones. A rather high cost of finished products is also associated with Kevlar. Nevertheless, such bulletproof vests do not save from bullets of large caliber, therefore, they can be used to protect against pistols and PPs.

Comprehensive protection of the human body from a shot is provided by ceramics. It is often used together with metal, so it can withstand even large calibers. This affects the weight of the product, which is quite difficult to wear for a long time.
