The DFNDR Armor Level IIIA Handgun Rated Backpack Armor (model E-IIIASA) is a hard stand-alone ballistic insert built from ultra-high molecular weight polyethylene (UHMWPE) fiber bound in a resin matrix. Independently tested to NIJ 0101.04 and NIJ 0108.01 protocols at NIJ-certified ballistic labs, this panel stops all Level IIIA-rated handgun threats evaluated at muzzle velocity. Spall-Tek coating reduces projectile fragment deflection after impact. Available in multiple dimensional options to maximize coverage inside your specific bag, backpack, or purse, and manufactured entirely in the USA with no TSA travel restrictions.

Who this is for

• Students and commuters: who carry a backpack daily and want discreet, NIJ-tested handgun-rated ballistic protection without adding bulk or triggering airport screening
• Parents and school administrators: looking for a panel that inserts into an existing bag rather than requiring a purpose-built tactical carrier
• Everyday carriers: who need a hard-panel insert with a trauma mitigation layer that fits almost any backpack, bag, or purse already in their rotation

Ballistic panel

The E-IIIASA panel uses UHMWPE fiber bonded with a resin matrix to form a rigid, hard stand-alone armor plate — not a soft-armor insert. That construction delivers Level IIIA handgun protection in the lowest areal density format DFNDR produces, keeping added weight to a minimum for everyday carry. Every threat in the rated profile is tested at muzzle velocity, the most demanding test condition, and the results are published in DFNDR's threat profile table for that model.

Each panel also incorporates a Trauma Mitigation Base that absorbs and dissipates impact energy to reduce blunt-force trauma behind the armor surface. Spall-Tek, applied to the panel, further reduces the deflection of projectile fragments after a round is stopped. The thin-profile variant is tested to the additional NIJ 0108.01 protocol, which governs ballistic-resistant protective materials beyond the standard plate test, providing an extra layer of independent verification for users who prioritize a slimmer profile.

Removability and conversion

The panel is designed to slide into almost any backpack, bag, or purse. Before ordering, measure your bag's main compartment — width, height, and depth at the widest and tallest points — and match those dimensions to the available insert sizes. Because the panel is a discrete insert rather than a sewn-in component, it transfers between bags without tools and can be removed for inspection or replacement. No permanent modification to your bag is required.

Capacity and organization

The insert occupies the main compartment of your existing bag. DFNDR offers multiple panel dimensions so you can select the size that fills as much of your bag's back panel as possible, maximizing the protected zone without blocking access to the rest of the compartment. All remaining pockets, sleeves, and organizers in your bag function normally with the panel installed.

Construction

The UHMWPE hard panel ships with Spall-Tek applied at the factory. It carries no TSA travel restrictions, so it moves through airport security without triggering additional screening. All panels are manufactured in the USA.

Specifications

Frequently asked questions

Can this backpack armor be shipped to my state?

It cannot be shipped to New York or Connecticut due to state body armor restrictions. It is also subject to US export regulations. Under 18 U.S.C. § 931, anyone with a federal felony conviction for a crime of violence is prohibited from purchasing or possessing body armor.

What NIJ level is this panel and what does that mean?

Level IIIA is a handgun-rated designation. This panel is independently tested to stop the full range of Level IIIA-rated handgun threats at muzzle velocity. It does not protect against rifle-caliber threats. For the specific rounds in the rated threat profile, refer to DFNDR's published threat profile table for model E-IIIASA.

Will this panel stop rifle rounds?

No. Level IIIA is a handgun-rated standard. Rifle-caliber threats — including 5.56x45 and 7.62x39 — exceed the IIIA rating and require a separate hard rifle-rated plate at Level III, Level III+, or Level IV.

Is the panel removable, or is it sewn in permanently?

It is removable. The panel is a discrete insert designed to slide into almost any backpack, bag, or purse. No permanent attachment is required, so it transfers between bags freely and can be removed at any time.

How do I choose the right panel size for my bag?

Measure the interior of your bag's main compartment at its widest and tallest points, then match those dimensions to the available insert sizes. If your measurements fall between sizes, select the larger option to maximize ballistic coverage. Contact us if you need help selecting the right size for your specific bag.

Does this panel have any TSA travel restrictions?

No. This panel carries no TSA travel restrictions and passes through airport security screening without triggering additional review.
