🛡️ Body Armor Level Guide
Pick an NIJ protection level to see what it's rated to stop, what it isn't, and whether it's soft armor or a hard rifle plate — with the full 0101.06 table alongside.
🛡️ NIJ Protection Levels
What is the NIJ armor level system?
It's the standard way body armor is classified. The NIJ 0101.06 standard defines a ladder of levels — from lightweight concealable soft armor rated for common handgun rounds up to hard plates rated for armor-piercing rifle fire. Knowing where a piece of gear sits on that ladder tells you what it can and can't protect against.
Use this guide to compare levels before you shop, understand a vest or plate's rating, and match protection to the threats you actually face. It's an informational reference to the published standard, not legal or safety advice — body armor is regulated in some regions, so check local laws, buy certified gear, and confirm any rating with the manufacturer.
❓ Frequently Asked Questions
What do the NIJ armor levels mean?
The U.S. National Institute of Justice (NIJ) Standard-0101.06 rates body armor by the threats it can stop. Soft-armor levels IIA, II, and IIIA cover progressively more powerful handgun rounds, while hard-plate levels III and IV are rated for rifle fire — Level IV including armor-piercing rifle rounds. Each level lists what it stops and, just as importantly, what it does not.
What's the difference between soft armor and hard plates?
Soft armor uses flexible layered fibers (such as aramid) that catch and spread the energy of handgun rounds; it's concealable and comfortable but cannot stop rifle fire. Hard plates are rigid inserts of steel, ceramic, or polyethylene worn in a plate carrier and are the only body armor rated for rifle threats (Levels III and IV).
Which armor level do I need?
That depends on the threats you realistically face and your local laws. Level IIIA is the top soft-armor rating and a common choice for concealable protection against handguns; Level III or IV hard plates are needed for rifle threats. This guide is informational only — assess your needs against certified, NIJ-tested gear and verify with the manufacturer.
Is it legal to own body armor?
Body armor is regulated in some regions and restricted for certain people in others. Rules vary widely by country, state, and locality, and can change. Always check the laws that apply to you before buying, and purchase only certified armor from a reputable maker.
