Whether you’re law enforcement, security, or a civilian interested in protection, this in-depth overview will give you the knowledge you need to understand and effectively use soft body armor.
What Is Body Armor
“What is body armor?” you may be asking. Body armor is protective gear designed to absorb or deflect physical damage, especially in dangerous environments where ballistic, or stab threats are prevalent. The use and history of body armor date back to ancient times when warriors used shields, breastplates, and helmets made from bronze, iron, and other metals. In the modern era, body armor has evolved significantly, employing sophisticated materials and technologies to provide effective protection against a wide range of threats.
What is Soft Body Armor
Soft body armor is a type of body armor that is flexible, lightweight, and comfortable for the wearer. It is typically made from high-performance fibers such as Kevlar, Twaron, or Dyneema. These fibers are woven together in a dense network that acts like a net to catch and deform a bullet, spreading the impact over a larger area to reduce the force of the blow. While soft body armor is most commonly used to protect against handgun and shotgun projectiles, different types of soft armor can provide protection against stab, spike, and edged blade threats.
Soft Body Armor vs Hard Body Armor
The main difference between soft body armor and hard body armor is the level of protection they offer and the types of threats they can withstand. Soft body armor is designed to be lightweight and flexible, making it ideal for everyday use by law enforcement for protection against common street-level pistol threats. However, it is not effective against rifle rounds.
Hard body armor, on the other hand, incorporates rigid plates made from materials like ceramic, steel, or ultra-high-molecular-weight polyethylene (UHMWPE). These plates can stop rifle rounds and lesser threats. However, hard body armor is generally heavier and less comfortable than soft body armor. It also covers less of the body due to weight and the rigid nature of the armor.

Different Types of Soft Body Armor
Not all soft armor is concerned with stopping bullets, some forms are just concerned with stopping hand-to-hand attacks. This is often seen worn by Correctional officers where knife attacks are their biggest concern. However, other varieties are purely ballistic, and only stop ballistic threats. Finally, some forms of soft armor will protect against ballistic threats and stab attacks. Let’s review the various types of soft body armor available today.
Stab-Resistant Armor
Stab-resistant armor is designed to protect against knife attacks. These often incorporate layers of tightly woven fabric like Kevlar, along with materials like laminate, to prevent the blade from penetrating the armor.
Spike Armor
Spike armor is designed to protect against attacks with sharp, pointed objects like ice picks or needles. It typically includes layers of very dense fabric that can catch and deform the spike, preventing it from reaching the wearer’s body. This is particularly important for corrections officers.
Edge Blade Armor
Edge Blade armor is designed to protect against attacks with bladed weapons such as machetes, axes, and swords. It may combine layers of high-performance fabric with materials like laminate to provide effective protection.
Bulletproof (Soft) Armor
Bulletproof armor is a type of soft body armor designed to protect against bullets. It incorporates layers of high-performance fabric that can catch and deform a bullet, spreading the force of the impact over a larger area.
Multi-threat Armor
Multi-threat armor is designed to provide protection against multiple types of threats, such as bullets, knives, and spikes. It often combines different materials and technologies to provide comprehensive protection. This has become popular in urban law enforcement where threats come in many forms.
Ballistic Blankets
Ballistic blankets are versatile pieces of soft body armor that can be used to provide temporary cover against ballistic threats. They can be draped over windows, doors, or other openings, or used to protect individuals in an active shooter situation.
Ballistic Shields
Ballistic shields are handheld shields made from high-performance materials that can stop bullets. While they are not technically “soft” armor, they can provide an additional layer of protection in conjunction with soft body armor.
Inflatable Armor
Inflatable armor, yeah it’s a real thing. This is a relatively new design thanks to the Navy and Coast Guard who need armor to be buoyant but still protective. It’s kind of like bulletproof floaties.Â
Concealable vs Tactical
Soft body armor really comes down to the vest or carrier. Concealed soft armor is specifically designed to be discreetly worn underneath clothing, ensuring it remains hidden from view while providing protection. Tactical soft armor is armor placed in a tactical vest or carrier designed to carry other accessories and identify the individual (as law enforcement for example).
Soft Body Armor Threat Levels & NIJ
The National Institute of Justice (NIJ) is an independent organization that sets the standards for body armor performance in the United States, and tests armor accordingly. The NIJ Standard 0101.06 is the current standard that classifies body armor by levels of ballistic performance.

Each of these threat levels as discussed below has been thoroughly tested to stop the specific calibers and types of bullets as described. However, no armor is 100% bulletproof these ratings indicate that the specific armor is able to stop the specific threats tested. Here’s an overview of the different levels of protection as per NIJ Standard 0101.06.
Level IIA Armor
Level IIA is the lowest level of protection currently available for body armor. Armor at this level is capable of protecting against 9mm, 40 S&W, and 45 ACP.
Level II Armor
Level II Armor is designed to protect against .357 Magnum Jacketed Soft Point (JSP) bullets.
Level IIIA Armor
Level IIIA protects against .357 SIG .44 Magnum and all lower threats. This is the most common level of protection for soft body armor.
Level III Armor
Level III is designed to protect against 7.62×51 M80 for 6 shots, with less than 44mm of back face deformation from the first two. Please note that Level III refers to hard armor or plate inserts that can stop rifle bullets. Soft body armor does not offer protection against rifle rounds.
Level IV Armor
Level IV is the highest level of armor and provides protection against 30-06 M2AP armor-piercing rounds for one shot, and then a shot from a lesser threat. Please note that Level IV refers to hard armor or plate inserts that can stop rifle bullets. Soft body armor does not offer protection against rifle rounds.
Soft Body Armor Materials
There are several materials commonly used in the production of soft body armor, each with its distinct advantages and disadvantages.

Kevlar
Kevlar is a synthetic fiber developed by DuPont in the 1960s. It’s a type of aramid fiber, similar in structure to nylon but with far superior strength and heat resistance.
Kevlar is five times stronger than steel on an equal-weight basis, making it extremely effective at stopping bullets. It’s also resistant to heat, cold, and moisture, making it suitable for use in a wide range of environments.
However, Kevlar can degrade over time, especially when exposed to light and certain chemicals. It’s also relatively expensive compared to some other materials.
Twaron
Twaron, a remarkable aramid fiber, emerges as another notable player in the field of ballistic protection. Developed by the renowned company Teijin, Twaron shares similarities with Kevlar in terms of its composition and properties. This high-performance synthetic fiber is renowned for its exceptional strength, making it an ideal candidate for applications requiring reliable resistance against impact and penetration.
Twaron is highly resistant to bullets, heat, cold, and moisture. It boasts remarkable tensile strength and impressive energy absorption capabilities, rendering it suitable for use in soft body armor. Its unique molecular structure grants it the ability to effectively dissipate and disperse the energy generated by projectiles, providing enhanced protection to the wearer.
Like Kevlar, Twaron can degrade over time, and it’s also on the more expensive side.
Spectra
Spectra is a high-density polyethylene (HDPE) fiber produced by Honeywell. It’s similar to Dyneema, which is also an HDPE fiber. Spectra is incredibly strong and lightweight, making it ideal for use in body armor. It’s also resistant to moisture, UV light, and chemicals.
However, Spectra is less effective against blunt force trauma compared to Kevlar or Twaron. It can also be more expensive than other materials.
Dyneema
Dyneema is a type of ultra-high-molecular-weight polyethylene (UHMWPE) fiber produced by DSM. It’s similar to Spectra in terms of its properties.
Dyneema is the world’s strongest fiber, with a tensile strength 15 times greater than steel on a weight-for-weight basis. It’s also highly resistant to moisture, UV light, and chemicals.
However, like Spectra, Dyneema is less effective against blunt force trauma than aramid fibers. It’s also relatively expensive.
UHMWPE
Ultra-high-molecular-weight polyethylene (UHMWPE), is a type of polyethylene with extremely long chains, which gives it high strength and toughness. UHMWPE is incredibly strong and lightweight, making it highly effective at stopping bullets. It’s also resistant to moisture, UV light, and chemicals.
Again, however, UHMWPE is less effective against blunt force trauma compared to Kevlar or Twaron. It can also be more expensive than other materials. Discover the differences between UHMWPE vs Kevlar and make an informed decision for your enhanced protective gear.
