The Spartan Armor Systems Flex Fused Core Level IIIA Concealment Package pairs two Flex Fused Core HG2/Level IIIA soft armor panels with the Spartan DL plate carrier, a purpose-built concealment shell designed to disappear under loose clothing. The panels are constructed from aramid fibers, assembled in Tucson, Arizona from American-made materials, and rated against handgun threats at the HG2/Level IIIA tier. The 10" x 12" panel weighs 0.95 lb at 0.35" thick; the 11" x 14" panel weighs 1.35 lb. Both panel sizes are available with the DL carrier in sizes S through 3XL.

Who this is for

• Plainclothes professionals: anyone who needs consistent ballistic protection without telegraphing its presence through a dress shirt, polo, or light jacket
• Everyday carriers: civilians and off-duty personnel who want pistol-rated armor they can actually wear all day without bulk or fatigue
• First-time armor buyers: shoppers who want a complete, ready-to-wear setup rather than sourcing carrier and panels separately

Threat coverage

The Flex Fused Core panels are rated at NIJ Level IIIA (HG2), the highest handgun-rated protection tier. Level IIIA armor is designed to defeat common pistol threats including .357 SIG FMJ, .44 Magnum SJHP, and 9mm at standard velocities. These panels do not protect against rifle-caliber rounds. For threats beyond handgun velocity ranges, a rifle-rated hard armor plate is required in addition to soft armor.

Concealability and comfort

The DL plate carrier is an ultra-minimalist shell engineered specifically for concealment. Two-inch low-profile adjustable shoulder straps and a four-inch adjustable cummerbund keep the silhouette flat and form-fitting. Worn under loose clothing, the carrier is virtually indiscernible. It accommodates both covert and overt use, so the same setup works under a jacket or worn openly over a shirt.

The Flex Fused Core panels measure 0.35 inches thick in the 10" x 12" configuration, a profile that conforms to the body rather than creating visible bulk. Aramid fiber construction provides the ballistic resistance while allowing the panel to flex with the wearer's movements during a full range of daily activity.

Care and maintenance

Soft armor panels should not be machine washed. Surface cleaning with a damp cloth is the recommended approach for routine maintenance. Store panels flat or rolled loosely in a cool, dry location away from prolonged UV exposure. The Flex Fused Core panels carry a 5-year warranty against manufacturer defects.

Specifications

Fit and carrier compatibility

The DL carrier accepts 10" x 12" and 11" x 14" plate pockets and is compatible with all Spartan Armor plates, though thinner armor profiles are recommended for best concealment performance. The cummerbund adjusts across a 4-inch range, and shoulder straps adjust independently. The size range runs S through 3XL. For a precise fit recommendation based on your measurements, contact us.

Frequently asked questions

What is NIJ Level IIIA and what does it stop?

Level IIIA (also designated HG2 under NIJ 0101.07 nomenclature) is the highest handgun-rated soft armor tier. It is designed to defeat .357 SIG FMJ FN and .44 Magnum SJHP along with a broad range of common pistol calibers. It does not stop rifle-caliber rounds. For rifle-rated protection, a hard armor plate rated Level III or Level IV must be added.

Will this stop rifle rounds?

No. Level IIIA soft armor is not rated against rifle threats. Rounds like 5.56x45 NATO, 7.62x39, and .308 Winchester exceed the velocity and penetration capability that soft armor panels can defeat. A rifle-rated hard plate worn in conjunction with soft armor provides combined protection against both threat tiers.

Can I conceal this under a normal shirt or jacket?

Yes. The DL carrier is designed specifically for deep concealment. The 0.35-inch panel profile and minimalist carrier construction sit flat against the torso. Under a loose shirt, untucked layer, or light jacket, the setup is virtually indiscernible. Tighter-fitting clothing will reveal the armor outline more readily.

How thick is the Flex Fused Core panel?

The 10" x 12" panel measures 0.35 inches (8.89 mm) thick. Thickness data for the 11" x 14" panel is not separately listed; contact us if thickness confirmation for the larger panel is critical to your selection.

Can I wash the soft armor panels?

No. Soft armor panels should not be machine washed or submerged. Clean the panel surface with a damp cloth as needed. Machine washing can delaminate the fibers and degrade ballistic performance, potentially voiding the warranty.

Can this package be shipped to my state?

This package cannot be shipped to New York or Connecticut due to state body armor restrictions. It is 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.
