Yes, in most of the United States, civilians can legally buy and wear body armor without a permit or special license. Federal law places no restrictions on law-abiding adults purchasing or wearing bulletproof vests. The main exceptions involve felony convictions and a handful of states with stricter rules.
Federal Law on Body Armor
Under 18 U.S.C. § 931, it is illegal for anyone convicted of a violent felony to purchase, own, or possess body armor. “Violent felony” refers specifically to crimes of violence as defined in federal law, not all felony convictions. There is one narrow exception: if an employer provides written certification that body armor is necessary for the safe performance of a lawful job, a person with a prior conviction may wear it during work.
For everyone else, there is no federal law preventing you from buying, owning, or wearing body armor in public, at home, or while traveling.
States With Stricter Rules
A few states go beyond the federal baseline. New York has the most restrictive law in the country. Effective July 6, 2022, New York prohibits civilians from purchasing or possessing body armor unless they work in an eligible profession. Eligible professions include police officers, peace officers, military personnel, and other jobs designated by the state Department of State where duties may expose workers to serious physical injury. You must present proof of your eligible profession at the time of purchase.
Connecticut requires that body armor be sold through in-person transactions, not online, and only to buyers who hold a gun permit, eligibility certificate, or ammunition certificate. The law exempts law enforcement, corrections staff, military reservists, federal firearms dealers, and EMS workers. Selling body armor outside these rules is a class B misdemeanor.
Other states may add their own penalties for wearing body armor during the commission of a crime, even if owning it is otherwise legal. If you live in a state you’re unsure about, your state legislature’s website will have the current statute.
What Body Armor Actually Stops
Not all body armor provides the same protection. The National Institute of Justice rates armor in tiers, and the differences are significant.
- Level IIA: Stops 9mm and .40 S&W rounds fired from short-barreled handguns. This is the lightest and thinnest option.
- Level II: Stops .357 SIG and .44 Magnum rounds from longer-barreled handguns. Still no rifle protection.
- Level IIIA: The highest soft armor rating, stopping the same calibers at higher velocities. Still handgun rounds only.
- Level III: Hard plates that stop 7.62mm full metal jacket rifle rounds.
- Level IV: Hard plates rated to stop .30 caliber steel core armor-piercing rifle rounds. The heaviest and bulkiest option.
One common misconception: a standard bulletproof vest will not reliably stop a knife. A blade can slip between the woven fibers that catch and slow a bullet. While soft armor offers some natural knife resistance, it is not specifically rated for stab protection. The NIJ has a separate spike and edged-blade rating system for stab-resistant armor, with three levels based on the force of the attack. If knife protection matters to you, look for armor that carries both a ballistic rating and a spike rating.
Concealed vs. Overt Armor
Body armor generally comes in two styles, and which one you choose determines how you’ll wear it and what protection level you can realistically carry.
Concealable vests are designed to be worn under clothing. They use soft panels typically between 4mm and 6mm thick, less than a quarter inch, so they add almost nothing to your visible outline. These are available up to Level IIIA and are the type most commonly worn by plainclothes law enforcement and civilians. The tradeoff is that with nothing rigid between you and the vest, your body absorbs more of the bullet’s impact energy, even though the round doesn’t penetrate.
Overt carriers, sometimes called plate carriers, are worn over clothing and can hold hard plates rated up to Level IV. They’re stiffer, distribute impact force better because the plate flexes away from your body, and most models include MOLLE webbing for attaching pouches and gear. You cannot comfortably wear hard plates under a shirt. These are primarily used by military personnel, tactical law enforcement, and security professionals.
How Long Body Armor Lasts
Body armor degrades over time. Soft armor panels, the kind made from woven synthetic fibers, have a typical service life of about five years under normal daily use. The NIJ requires manufacturers to offer a minimum five-year warranty. Hard ceramic and polyethylene plates last longer, generally seven to eight years. Civilian armor that sees lighter use often carries warranties of five to ten years.
The main things that shorten armor life are moisture and physical wear. Sweat, water submersion, and certain chemicals break down the fibers or their protective coatings. Ceramic plates are highly resistant to abrasion but can crack if dropped or crushed. Steel plates need careful moisture management to prevent corrosion. If your armor has been soaked, sat on daily for years, or taken a hard impact, it may no longer perform to its original rating regardless of its age.
Flying With Body Armor
The TSA allows body armor in both carry-on and checked luggage. That said, the final decision at any checkpoint rests with the individual TSA officer, so there is a small chance you could be asked to check it or have it inspected more closely. If you’re flying to or through New York, Connecticut, or another state with purchase or possession restrictions, make sure you’re in compliance with that state’s law before you arrive.
