What Makes A Bulletproof Vest Bullet-Resistant?

To be precise, ballistic or bulletproof vest are not “bulletproof”. Rather, they are varying degrees of “bullet resistant. “Most police-type vests will stop most all handgun rounds. But how do they usually work? It’s the result of the use of “Aramid” fibers. Aramid is a trading name for a tough synthetic fiber that can be tightly woven together. Layers of this material, with the “grain” running in opposite directions, are laid up in sufficient numbers so that when a bullet strikes, the impact is spread over a large area rather than a small one.

The result is a considerable impact but no penetration. The person wearing the vest will often have a saucer-sized bruise at the point of impact.

How ‘Bulletproof’ Are Bulletproof Vests – At What Caliber And Range Would They Fail To Stop A Bullet With Lethal Results?

Depends on the bulletproof vest. Personal armor comes in 3 major “Levels,” with one notable sublevel defined by the National Institute of Justice. The level of protection of ballistic plates depends on their internal construction, which commonly adds bulk to the design that’s more obvious when the vest is worn. So, the minimum level of protection suitable for the 95th-percentile threat a person is likely to face is typically favored to save weight, increase flexibility and agility, and lower cost.

Level II

The lowest level of protection commonly offered; Level II is designed to stop a low-intensity incoming fire from most non-armor-piercing handguns. Clothing to protect against a relatively low likelihood of an imminent deadly threat. Level II is commonly exeute as a thin, low-profile Kevlar vest or as panels integrated into other garments or vehicles.

Level IIIa

Equivalent in rated protection to Level II in that it’s primarily designed to stop non-armor-piercing handguns. Level IIIa is designed to be more durable for daily wear and is the most common level used by patrol police officers in the U.S.

Level III

Designed to stop most non-armor-piercing small arms. This is the most common level used by SWAT and other special response teams when resistance to the wearer is to be known. It is rated to withstand a 7.62x51mm NATO M80 cartridge, a 147gr FMJ non-armor-piercing bullet traveling at 2750 ft/s. Common rifle cartridges available in the U.S. and elsewhere can penetrate this vest. Still, it is resistant to most weapons fire the wearer is likely to encounter in any civilized country. It’s commonly known as an externally-worn vest with additional coverage around the neck, shoulder, and flanks or as a “plate carrier” with built-in Level II/IIIA protection plus pockets for armor plates worn outside the Kevlar layers.

Level IV:

The maximum classification under the NIJ system, Level IV armor is known to stop armor-piercing projectiles, and is familiar by firing a .30-caliber A.P. round at a sacrificial example vest. Armed Forces in combat zones and integrated into “max-level armored” civilian vehicles.

However, this level is not meant for what it must protect against. Look for the Features you need, then buy a bulletproof vest for sale in your Size from a Reputable Company.
