The DFNDR Armor Level III+ Rifle-Rated Backpack Insert (Model E-IIIPSALW-08B) is a hard stand-alone UHMWPE ballistic panel engineered to defeat rifle-caliber threats at one of the lowest areal densities available in a backpack-format insert. Built from ultra-high molecular weight polyethylene fiber bound in a resin matrix and equipped with Spall-Tek fragmentation mitigation, this panel inserts into almost any backpack, bag, or purse and is independently tested to NIJ 0108.01 protocol at NIJ-certified ballistic laboratories. Multiple dimensional options let you match the panel to your specific pack compartment for maximum coverage.

Who this is for

• Students and commuters: who carry a backpack daily and want rifle-rated ballistic coverage without adding significant bulk or weight to their load.
• Travelers and professionals: who need a discreet hard armor insert that clears TSA checkpoints and fits standard laptop bags or carry-on packs.
• Preparedness-minded civilians: who want a standalone panel that drops into existing bags and provides coverage against common AK and AR platform threats.

Ballistic panel

The Level III+ panel defeats Mild Steel Core Chinese 7.62x39 and PS Ball Russian 7.62x39 AK-47 threats — rounds that standard NIJ Level III UHMWPE panels routinely fail to stop. It also defeats standard lead-core .308, 7.62x51, .223, and 5.56x45 threats. All rounds in the threat profile are tested at muzzle velocity. The construction pairs UHMWPE fiber with a resin matrix binder to produce a rigid, hard stand-alone panel — no soft armor backer required. Spall-Tek is integrated into the panel to further reduce deflection of projectile fragments, keeping secondary fragment energy directed away from the user.

The panel is independently tested to NIJ 0108.01 protocol at NIJ-certified ballistic laboratories. This is a Special Threat Rated Level III+ designation; it is not listed under NIJ 0101.06 Level III on the NIJ Compliant Products List, which does not cover the MSC and PS Ball threat parameters this panel is designed to defeat.

Removability and conversion

The insert is a stand-alone hard armor panel with no attached carrier — it slides directly into your backpack's main compartment or a dedicated sleeve. Before purchasing, measure the interior width, height, and depth of your pack at its widest and tallest points, then match those dimensions against the available panel sizes. Multiple dimensional options are offered so you can select the largest panel your compartment will accept for the broadest coverage area.

Capacity and organization

Because this is a bare armor insert rather than a complete backpack, capacity and organization depend entirely on the host pack you pair it with. The panel is designed to fit into almost any backpack, bag, or purse. DFNDR provides a sizing chart and a step-by-step measuring guide — measure width, height, and depth at the widest and tallest interior points, then select the closest available panel size.

Construction

Core material is UHMWPE fiber bound with a resin matrix, produced entirely in the USA. The hard panel construction means it holds its shape inside any compartment and does not require a frame or insert sleeve to function. Spall-Tek is built in at the manufacturing stage — it is not an aftermarket coating. The panel carries no TSA restrictions and can be transported through airport security checkpoints.

Specifications

Frequently asked questions

Can this backpack insert be shipped to my state?

This panel 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 is it NIJ Certified?

It is Special Threat Rated Level III+ and independently tested to NIJ 0108.01 protocol at NIJ-certified ballistic laboratories. This designation is not the same as a CPL listing under NIJ 0101.06 Level III. The Level III+ rating covers MSC and PS Ball 7.62x39 threats that the standard NIJ Level III test matrix does not include.

Will this panel stop rifle rounds?

Yes. It defeats Mild Steel Core Chinese 7.62x39, PS Ball Russian 7.62x39, standard lead-core .308 / 7.62x51, .223, and 5.56x45 — all tested at muzzle velocity. It is specifically engineered for the MSC and PS Ball AK-47 threats that standard Level III panels do not reliably stop.

Is the panel removable, and can I move it between bags?

Yes. The insert is a bare hard panel with no attached carrier, so it moves freely between any bags whose compartment dimensions accommodate it. Measure each new bag before transferring to confirm coverage area.

What size panel do I need for my backpack?

Measure the interior width, height, and depth of your pack's main compartment at the widest and tallest points. Match those dimensions to the available panel sizes in the sizing chart and select the largest panel that fits your compartment for maximum coverage. Contact us if you need help matching a panel size to your specific bag.

Does this panel have any TSA restrictions?

No. There are no TSA restrictions on this panel, and it can be transported through airport security checkpoints without issue.
