The world of body armor can be complex and intricate with numerous specifications, materials, and designs to understand. In this post we will focus on one specific and common piece, Level IIIA body armor. We will break down what exactly Level IIIA body armor is, how it is made, where it fits among other armor levels, its National Institute of Justice (NIJ) certification, as well as the importance of body armor

What is Level IIIA Body Armor?

Level IIIA body armor is specifically designed to offer protection against the vast majority of handgun rounds. 

Formerly made predominantly from Kevlar, and now UHMWPE (Ultra high molecular weight polyethylene) it is created using multiple layers of woven fibers. These layers are then compressed together under high temperature and pressure conditions to form a protective panel.

Level IIIA body armor occupies a unique space within the armor level spectrum, offering the highest protection for pistol rated armor. 

Meanwhile, Level IIIA body armor falls short of the rifle protection of Levels III and IV, which are designed to withstand rifle rounds.

Is Level IIIA Body Armor NIJ Certified?

The National Institute of Justice sets standards, evaluates, and certifies body armor in the U.S. Level IIIA armor sits between Level II pistol and III hard rifle armor on the NIJ rating scale of body armor levels

To be certified Level IIIA, armor is specifically tested against .357 SIG FMJ and .44 Magnum Semi Jacketed Hollow Point. 

If the armor can stop these threats it will not have a problem with lesser threats, such as 9mm, and is certified NIJ Level IIIA. 

However, as with all types of body armor, it’s important to note that no armor is completely bulletproof, and Level IIIA is not designed to protect against rifle rounds.

Is Level IIIA a Soft Armor?

Yes, primarily but not exclusively. There are level IIIA hard body armor plates that are remarkably thin and lightweight. The term “soft” refers to the flexible, wearable nature of the armor, which is unlike the rigid plates found in Level III and IV armors.

Soft body armors are primarily made from high-tech synthetic fibers such as Kevlar or Ultra High Molecular Weight Polyethylene (UHMWPE). These materials have a remarkable ability to absorb and disperse the energy of a bullet impact, significantly reducing the likelihood of injury.

Kevlar, the most commonly known material, is a type of aramid fiber that is both lightweight and extremely strong. On the other hand, UHMWPE is a type of polyethylene with high resistance to impact and is also often used in the manufacturing of bulletproof vests. UHMWPE is now the primary material used in level IIIA armor because it is lighter and stronger than Kevlar, creating a lighter, thinner panel capable of defeating the same threats. 

One of the main reasons individuals may choose soft body armor, such as Level IIIA, is for its superior comfort and flexibility compared to hard armor. Soft armor can be worn covertly under clothing, making it an ideal choice for protection, especially for law enforcement officers or security who need their armor to maintain a low profile.

What Does Level IIIA Body Armor Stop?

Level IIIA body armor is specifically designed and tested to stop the vast majority of handgun rounds. This includes .44 Magnum and .357 SIG, which are some of the most powerful handgun bullets. Level IIIA can stop lower velocity rounds such as 9mm, 40 S&W, and 45 ACP, providing protection against most handgun threats. Additionally, level IIIA will stop most shotgun rounds.  

However, it’s important to remember that while Level IIIA body armor offers protection against these rounds, it is not designed to protect against rifle rounds or armor piercing ammunition.

Benefits of Level IIIA Body Armor

  • Comfort and Flexibility: Level IIIA body armor is soft and flexible, making it comfortable to wear for extended periods of time. It can be easily worn under clothing, which is beneficial for covert operations or any situation where discretion is necessary.
  • Lightweight: The materials used in Level IIIA body armor, such as Kevlar or UHMWPE, are lightweight. This reduces the burden on the wearer, allowing for greater mobility and less fatigue over long durations.
  • High Protection Against Handgun Rounds: Level IIIA body armor can effectively stop most handgun rounds, including high velocity bullets from a .44 Magnum or .357 SIG. This makes it a solid choice for law enforcement officers or security personnel who are more likely to encounter threats from handguns.
  • Multiple Hits Capability: Level IIIA soft armor can take multiple hits in the same general area without compromising the wearer’s safety.
  • Stab and Slash Resistance: While it’s not primarily designed for this, soft armor can provide a certain level of protection against attacks from knives or other sharp objects.

Drawbacks of Level IIIA Body Armor

  • Limited Protection Against Rifle Rounds: Level IIIA body armor is not designed to stop rifle rounds. For situations where there’s a potential threat from rifles, higher levels of body armor (Level III or IV) would be more suitable.
  • Not Ideal for All Climates: The materials used in Level IIIA body armor can degrade in extreme temperatures and humidity. This will shorten the overall lifespan of the armor so care should be taken to minimize the effects of the environment. 
  • No Armor Piercing Protection: Level IIIA cannot protect against armor piercing rounds. For these types of threats, Level IV hard armor plates are needed.

What Is Level IIIA Body Armor Made Of?

Level IIIA body armor is typically made from advanced woven fibers, such as Kevlar, Twaron, or UHMWPE (Ultra High Molecular Weight Polyethylene). These materials are known for their exceptional strength-to-weight ratio and flexible properties.

Kevlar is an aramid fiber and has a long standing reputation in the body armor industry. It has excellent heat resistance, robust tensile strength, and is lightweight. However, it may not handle blunt force as effectively as UHMWPE.

UHMWPE is a type of polyolefin made up of extremely long chains of polyethylene. Its high tensile strength, combined with its lightweight and flexible properties, make it an excellent material for body armor. UHMWPE also has a higher energy absorption rate than Kevlar, which translates to improved protection against blunt force trauma.

Level III Vs IIIA Body Armor

While Level III and IIIA body armor are both designed to protect the wearer, they cater to different threat levels.

Level III Body Armor is hard armor, made from materials like polyethylene, steel, or ceramic. It’s designed to stop rifle rounds, such as the 7.62×51. The downside is that these plates are heavier, offer less coverage, and lack the flexibility of Level IIIA armor.

Level IIIA Body Armor is soft armor, although it is also made into hard armor plates, and is designed for comfort and flexibility. It’s made to stop handgun rounds and shotgun blasts. However, it won’t provide protection against rifle rounds that Level III armor would.

Choosing between Level III and Level IIIA body armor comes down to the specific threat level you’re expecting to face.

Selecting The Right Level IIIA Armor For You

Selecting the right body armor depends on various factors such as the nature of the threat, mobility needs, comfort, duration of use, and discretion. If you are in a role where there’s a higher likelihood of encountering handgun threats, Level IIIA could be the right fit. Its lightweight and flexible design makes it easy to wear without compromising mobility. Plus, it can be concealed under clothing, making it suitable for covert operations.

However, if there’s a potential threat from rifle rounds or armor piercing ammunition, you might want to consider hard armor options like Level III or Level IV. Remember, the best armor for you is the one that matches your specific requirements and circumstances. Always evaluate the options and make an informed decision.
