What is Level IIIA body armor?

Hey there! As a body armor supplier, I've been getting a lot of questions lately about Level IIIA body armor. So, I thought I'd take the time to break it down for you and explain what it is, how it works, and why it might be the right choice for you.

What is Level IIIA Body Armor?

Level IIIA body armor is a type of ballistic protection that's designed to stop a variety of handgun rounds, including 9mm,.40 S&W, and.44 Magnum. It's one of the highest levels of protection available for soft body armor, which means it's flexible and can be worn comfortably under clothing.

The National Institute of Justice (NIJ) sets the standards for body armor in the United States. Level IIIA is defined as armor that can stop all handgun rounds up to.44 Magnum fired from a revolver with a 6-inch barrel. This includes both full metal jacket (FMJ) and jacketed hollow point (JHP) rounds.

How Does Level IIIA Body Armor Work?

Level IIIA body armor works by using a combination of materials to absorb and disperse the energy of a bullet. The most common materials used in Level IIIA armor are Kevlar, Spectra, and Twaron. These materials are strong and lightweight, and they're able to stop bullets by creating a barrier that the bullet has to penetrate.

When a bullet hits Level IIIA body armor, the fibers in the armor stretch and deform, absorbing the energy of the bullet. This causes the bullet to slow down and eventually stop. The armor also helps to distribute the force of the impact over a larger area, reducing the risk of injury to the wearer.

Types of Level IIIA Body Armor

There are several different types of Level IIIA body armor available, each with its own advantages and disadvantages. Here are some of the most common types:

  • Concealable Body Armor Vest With Plates NIJ IIIA: This type of armor is designed to be worn under clothing and is typically made from a combination of soft armor panels and hard armor plates.

How to Choose the Right Level IIIA Body Armor
