The HighCom Armor Guardian 3i10m is a 100% DSM Dyneema UHMWPE hard armor plate rated Level III and special threats in conjunction with Level IIIA soft armor. Built through XTclave ultra-high pressure consolidation, it measures just 0.47 inches thick — under half an inch — and weighs as little as 1.3 lbs in SAPI XS cut. It is independently tested by an NVLAP-accredited, NIJ-approved laboratory to meet or exceed ballistic resistance as specified under NIJ Standard 0101.06. Available in a 10x12 Shooters Cut and SAPI Multi Curve cuts from XS through XL, the 3i10m is purpose-built for professionals who need rifle-rated protection without the bulk or weight of ceramic or steel.

Who this is for

• Law enforcement officers: who need rifle-rated coverage in a low-profile platform that disappears under a duty uniform or concealable carrier
• Security and protective detail personnel: who carry plates for extended shifts and need to minimize cumulative weight across a full day
• Military and government personnel: requiring ICW-rated Level III and special-threat protection in the lightest possible UHMWPE package

Ballistic performance

The Guardian 3i10m is rated Level III ICW Level IIIA soft armor under NIJ Standard 0101.06, meaning the plate must be worn in conjunction with a Level IIIA soft armor backer to achieve its rated protection level. The plate is constructed from 100% DSM Dyneema UHMWPE — the same Dyneema fiber platform used across professional-grade body armor systems — consolidated under XTclave ultra-high pressure processing. At an areal density of 2.47 psf (12 kg/m²) and a thickness of just 0.47 inches (12 mm), it delivers rifle-rated coverage at a profile that ceramic and steel plates cannot match.

Beyond the NIJ 0101.06 Level III rating, the 3i10m is independently tested against two additional special-threat rounds: 7.62x39mm mild steel core and 5.56x45mm M193. Those threats fall outside the standard NIJ Level III test protocol, and defeating them at the tested velocities places this plate in a category above baseline Level III performance. The exterior cover is available in either Polyurea Rhino Extreme 11-50 anti-spall coated system or 1000D Cordura textured nylon.

Ballistic test data

Plate compatibility and cut geometry

The 3i10m ships in Multi Curve geometry across all sizes. The 10x12 variant uses a Shooters Cut profile; SAPI sizes run from XS (7.25 x 11.5 in) through XL (11 x 14 in) in a true SAPI cut. Multi Curve geometry matches the contour of most modern plate carriers that accept SAPI-pattern plates, distributing contact evenly across the chest and back without pressure points at the edges. The Shooters Cut 10x12 fits the majority of plate carriers designed around that standard size. Contact us if you need fitment confirmation for a specific carrier model before ordering.

Specifications

Fit and carrier compatibility

The 10x12 Shooters Cut variant seats in any plate carrier with a standard 10x12 plate pocket. SAPI-cut sizes (XS through XL) require a carrier with SAPI-pattern pockets — common in military-spec and law-enforcement-spec plate carriers. Because this plate is rated ICW Level IIIA, the carrier must also accommodate a soft armor backer panel behind the hard plate to achieve the published protection level. Verify that your carrier's plate pocket depth and backer pocket accommodate both components before ordering, or contact us for guidance.

Frequently asked questions

Is this plate NIJ Certified or NIJ Listed?

The Guardian 3i10m is independently tested at an NVLAP-accredited, NIJ-approved laboratory to meet or exceed NIJ Standard 0101.06 Level III threat parameters. For current NIJ Compliant Products List (CPL) listing status, check the NIJ CPL directly at nij.ojp.gov.

What does "ICW Level IIIA" mean, and do I need a soft armor backer?

Yes — a Level IIIA soft armor backer is required. ICW stands for "in conjunction with." The 3i10m achieves its Level III and special-threat ratings only when worn over a Level IIIA soft armor panel. Using the plate alone, without a IIIA backer, does not replicate the tested protection level. Plan your system to include a compatible soft armor insert behind this plate.

What rounds does the 3i10m stop?

When worn ICW Level IIIA soft armor, the plate is tested to stop 7.62mm FMJ Steel Jacketed M80 at 2,780 ft/s (NIJ 0101.06 Level III), 7.62x39mm mild steel core at 2,400 ft/s (special threat), and 5.56x45mm M193 at 3,250 ft/s (special threat). All three are rifle-caliber threats. The plate is not rated against armor-piercing rifle threats such as 5.56x45mm M855A1 or 7.62x51mm AP.

What is the difference between Shooters Cut and SAPI Cut?

Shooters Cut plates have squared-off upper corners that maximize coverage area while allowing a higher rifle stock position. SAPI Cut plates have notched upper corners that match the SAPI/ESAPI pocket geometry found in military-spec carriers. The 3i10m's 10x12 variant ships in Shooters Cut; all other sizes (XS–XL) ship in SAPI Multi Curve. Choose based on your carrier's plate pocket format.

How thin and light is this plate compared to ceramic or steel?

At 0.47 inches thick and a starting weight of 1.3 lbs (SAPI XS), the 3i10m is substantially thinner and lighter than comparable ceramic plates, which typically run 0.8–1.1 inches and 5–8 lbs, and steel plates, which typically run 0.25–0.35 inches but weigh 7–10 lbs per plate. The UHMWPE construction delivers the weight advantage; the XTclave process delivers the thinness.

Can this plate be shipped to my state?

This plate cannot be shipped to New York or Connecticut due to state body armor restrictions on civilian purchases. It is subject to U.S. export regulations under EAR and ITAR. 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.
