Backpack Body Armor (What it stops and how to use it)

Backpack body armor has been marketed to the public for quite a few years. Before that, people were buying soft or hard armor and putting it in their backpacks. Purchasing purpose-made backpacks and armor or just buying the armor and putting it in your current pack are both viable options if you’re looking to get into backpack body armor.

Backpack body armor is relatively new to the market. It’s a way to conceal the fact that you have body armor with you by carrying an armored panel or plate in a backpack. The most common level of protection provided by backpack body armor is level II and level IIIA.

Deciding to buy backpack armor is pretty much a no-brainer. Whether for your daughter’s school backpack or your briefcase that you carry to work every day, it makes sense to spend the money just in case.

The real decision is figuring out what kind of armor you need. What do the different levels mean? How heavy is it? How are you supposed to use it? The questions go on and on.

Keep reading, and we’ll answer all those questions and more!

Armor Comes in Different Ratings

Body Armor Ratings Explained

Armor is rated based on a standard by the National Institute of Justice. These ratings are often referred to as NIJ Ratings.

These ratings are based on the stopping power and the amount of protection you get from the blunt force of the bullet. (The NIJ considers less than 1.7″ of blunt trauma to be passing.)

Armor, for our purposes, is divided into soft and hard varieties.

We’re interested in soft armor rated at II-A, II, and III-A. These are rated to stop various calibers of handgun ammo.

Soft armor is made up of many layers of aramid. Kevlar is the best-known brand.

Other things to consider are that soft armor can defend against slashing knife attacks but not penetrating/stabbing attacks.

Soft body armor can also protect against frag from things like IEDs. I had a piece of frag from a 130mm projectile used in an IED get stopped by soft armor I was wearing in Iraq.

Body Armor Level Effective Against These Calibers
II-A 9 mm FMJ (Full Metal Jacket) at ~1,090 fps

.40 S&W Full Metal Jacket at 1,025 fps

II 9 mm FMJ, at ~1,175 fps

.357 JSP at ~1,400 fps

III-A 9 mm FMJ at ~1,400 fps

.44 Magnum Semi-Jacketed Hollow Point at ~1,400 fps

Hard armor that we’re looking at is level III and level IV. These are designed to stop rifle-caliber ammo.

Hard armor for civilian use is normally made of hardened steel designed to stop projectiles. Ceramic plates are also available.

Body Armor Level Effective Against These Calibers
III .308 Winchester Full Metal Jacket =
7.62 X 51 mm NATO6 rounds at ~ 2,750 fps
IV .3006 Armor-Piercing
.30 M2 APOne round at ~ 2,850 fps

What is level 5 body armor? How about level 6 body armor or level 7 body armor?

There is no such thing in the current NIJ rating system. Some people seem to be pushing these levels as legitimate, but there isn’t an official level 5, level 6, or level 7 body armor as of this writing.

We’ll discuss the pros and cons of hard and soft armor.

Body Armor Strengths and Weaknesses

Pros and Cons of Different Armor Types

Soft Armor

Pros: Soft armor has two main advantages. It’s very light, and it can flex. This makes soft armor the most concealable type of backpack body armor.

Soft armor is much more concealable than hard armor.

Cons: Soft armor has a major drawback…it doesn’t protect as well as a heavy steel plate. This is fine if your main threat is handgun rounds. If you believe your main threat is from someone with a rifle, then soft armor doesn’t do much to help in that situation.

Soft armor deteriorates much faster than hard armor. (The shelf life is normally around five years.) This degradation is even faster if it’s getting wet or sweaty regularly.

Hard Armor

Pros: Hard armor provides the best protection that you can get. Shelf life is normally around 20 years for steel plates. (It’s likely much longer than that.)

Hard armor can have a shelf life of over 20 years!

Steel armor can usually take many rounds of the rated caliber before showing any signs of wear. Even then, it retains most of its protective capabilities.

Cons: By being able to stop nearly every threat, most hard armor needs to be heavy. It is also less concealable than soft armor.

Different hard armor plates are made of composite materials like plastic or ceramic. These counter the main disadvantage of weight but normally degrade faster and cannot reliably take more than one round. They’re also thicker than steel plates.

Selecting Your Armor

The first thing you will want to do is figure out what your most likely threat is. As we said earlier, if you expect to encounter rifle fire, then soft armor doesn’t do much for you.

The second thing you should consider is weight. Level III and IV plates are heavy, while soft armor panels weigh around a pound.

If I sent a kid to school every day, I would give them a level III-A panel to put into the back of their backpack. They’d never notice it, and it would give them some protection if it ever came down.

Some companies make purpose-built backpacks with special pockets to hold armor panels and plates. AR 500 Armor and Bullet Blocker are good places to find these backpacks. Bullet Blocker is interesting because they offer a full range of backpacks, from little girly teal backpacks to tactical packs.

If you’re looking for something that in no way says armor to anyone looking on, then you’ll probably want to buy the bag and plates separately. Any pack with a bladder pouch makes a good candidate for armor. Just make sure you measure well before you order the plates, so you’re sure you’re getting the right size.

Something like this CamelBak BFM Mil Spec Antidote is great for sliding a plate into; no one would guess your Camelbak can stop bullets.

If you need level III armor, you can find some lightweight plates from AR 500 Armor. They’re about 5 lbs. You can find level III armor at around 3 lbs, but the composites are expensive and about six times the cost of lightweight steel plates!

How Do You Use Backpack Armor?

Backpack armor has three logical uses in my mind.

  1. Wear the armor like a backpack to protect your vital organs as you run from the gunman. This is the thing that makes me believe that backpack armor has a practical purpose for children.
  2. Hold the backpack (or briefcase) as a shield as you retreat from the gunman. Make sure you cover vital organs as much as possible as you retreat.
  3. Wear the backpack on the front of your torso (or hold the briefcase/backpack in front of you) so your vital organs are protected as you advance on the gunman.

Whatever you do to get the armor between you and the incoming rounds is fine!

Traveling with Body Armor

Armor is allowed in both checked bags and carry-on bags.

Straight from the TSA website: “Generally, body armor is allowed in carry-on or checked bags. Please note, however, that even if an item is generally allowed, our officers make the final decision on whether an item is allowed through the checkpoint.”

If you plan on purchasing armor, check the laws in your area before you do. Some places in the US have restrictions on armor, and many countries outside the US restrict body armor in one way or another.

Backpack Armor…do you Need it?

If you’ve never considered the practical uses of backpack armor, hopefully, this article has opened your eyes to the possibilities that are out there to add an extra layer of protection for you or a loved one.

A simple 1 lb armor panel in a pack can mean the difference between life and death! Don’t just look at backpack body armor as a fad. It’s something that you should seriously consider.
