It should be said at the outset that choosing a suitable and reliable 'natelle' is not a simple matter. The majority of first-time users of the body armour believe that the armour offered by the market will protect them from any bullet. First, let us discuss the types of body armour offered. We will divide them into police and security vests and military vests

Police and security

Law enforcement officers and security guards came into conflict with armed criminals as a way of life, which is why the need for good quality body armour is so important.

The police and security services are primarily intended for level 1 and 2 body armour suits.

The specifications of the Level 1 waistcoats are as follows: protection against pistol bullets, weight of 2 to 3.5 kg and flexible armor inserts.

The main characteristics of the waistcoats of the 2nd level of defense: include armor with rigid armor elements, weight from 2.2 to 6.2 kg.

From level 3 the waistcoats are able to protect against bullets fired from a Kalashnikov assault rifle.

What is Kevlar?

Kevlar fibre was invented in 1965 by the US corporation DuPont. Kevlar is an aramid synthetic fibre, it is claimed by its developers to be five times stronger than steel at equal weight. Since the 1990s, DuPont has been producing higher-strength waistcoats - Kevlar Nt (Kevlar 129) and Kevlar KM 2.

The Kevlar series models are worth describing in more detail. For example, a special prison waistcoat will protect prison staff from cutting and stabbing. The waistcoat is made up of several layers of Kevlar® fibres and protects against stabbing with a razor blade. The lightweight (about 1.4 kg) and flexible design of the waistcoat allow for concealed wear.

The police 'sleeveless' Kevlar waistcoat in the AS series is built from treated layers of Kevlar and resists bullets from a 9mm all-metal jacketed Parabellum pistol. The so-called barrier effect of Magnum pistol bullets has been reduced by almost 25 per cent. The waistcoat, which weighs 2.5 kg, also provides protection against stabbing with cold steel weapons.

Military flak jackets

In principle, the body armor waistcoats can include those that protect against machine gun and rifle shots as well as those that protect against shrapnel. Usually the army waistcoat only reliably protects the armour on the front, with anti-shrapnel inserts on the back.

Kevlar and Twaron waistcoats remain popular. Not all Kevlar waistcoats offer protection against high velocity rifle bullets and bayonet blows. Kevlar waistcoats coated with a ceramic plate are now being developed.

Anecdotal evidence from recent armed conflicts suggests that 75% of fatal injuries are caused by shrapnel and buckshot, and only 20% by aimed bullets. Most of the anti-shrapnel waistcoats purchased by the army are made from Twaron fibre. But remember, anti-shrapnel waistcoats provide little or no protection against bullets.
