The Caliber Armor CaliberHX Level IIIA Hard Armor Speed Plate is a UHMWPE-based pistol-rated hard plate engineered for extended wear, high-mobility operations, and tactical applications where reduced carry weight matters. At just 0.29 inches thin, the 10x12 variant weighs 1.33 lbs and the 8x10 weighs 1.0 lb. The multi-curve geometry fits the body naturally. A waterproof PolyShield polyurea finish seals the plate against moisture. Manufactured in Louisville, Kentucky. Available in 10x12 and 8x10, sold individually.

Who this is for

• Law enforcement on extended patrols: the sub-1.5 lb weight and multi-curve profile reduce fatigue across 8–12 hour shifts without sacrificing Level IIIA pistol protection.
• Tactical teams running speed operations: the SAPI-style higher cut and multi-curve UHMWPE construction keep the plate out of the way during dynamic movement and high-speed maneuvers.
• Concealed-carry and low-profile users: at 0.29 inches thin, the CaliberHX seats flush in concealable carriers, including Caliber Armor's own Gray Man Concealable Carrier, without visible printing.

Ballistic performance

The CaliberHX is rated at Level IIIA, covering the full spectrum of common handgun threats. Ultra High Molecular Weight Polyethylene (UHMWPE) delivers this protection at a fraction of the mass of steel or ceramic plates at the same threat level. The plate is multi-shot rated, meaning it maintains structural integrity and ballistic performance across repeated impacts rather than single-round exposure.

The PolyShield polyurea finish is a waterproof exterior coating applied across the plate surface. This finish also serves as a protective layer that reduces fragmentation risks associated with plate impacts. The plate is buoyant — it will not sink if submerged — which extends its utility to maritime and water-crossing environments.

This plate is designed and tested to meet and exceed NIJ requirements for Level IIIA. It is not rated against rifle threats. Users requiring rifle-rated protection should select a Level III or Level IV plate system.

Plate compatibility and cut geometry

The CaliberHX uses a higher cut, SAPI-style shape that clears the shoulder and arm on both the 10x12 and 8x10 sizes. The multi-curve profile matches the natural contour of the torso, distributing contact pressure evenly across the chest and reducing edge discomfort during prolonged wear. Both sizes seat in standard plate pockets sized for 10x12 or 8x10 SAPI-style plates. Caliber Armor specifically pairs this plate with the Gray Man Concealable Carrier for users prioritizing a low-profile setup. Contact us to confirm fitment with a specific carrier before ordering.

Specifications

Fit and carrier compatibility

The 0.29-inch profile and SAPI-style higher cut allow the CaliberHX to seat in most standard plate carriers with 10x12 or 8x10 plate pockets. The multi-curve geometry is designed to conform to the chest without adapter pads or additional shaping. Caliber Armor recommends the Gray Man Concealable Carrier as a purpose-matched pairing. Contact us if you need fitment confirmation for a specific carrier model before purchase.

Frequently asked questions

What rounds does this plate stop?

The CaliberHX is rated at Level IIIA, which covers the full range of common handgun calibers. It is not rated against rifle threats. For rifle-rated protection, Level III or Level IV plates are required.

Is this plate NIJ Listed or NIJ Certified?

The CaliberHX is tested to meet and exceed NIJ Level IIIA requirements. For current NIJ Compliant Products List status, check the NIJ CPL at nij.ojp.gov directly.

What is the difference between this plate and a soft Level IIIA panel?

Both offer Level IIIA protection, but the CaliberHX is a hard plate made from UHMWPE. At 0.29 inches thin and 1.0–1.33 lbs, it is thinner and lighter than most soft IIIA panels of equivalent size, and it carries a multi-shot rating with a waterproof, buoyant construction that soft panels typically do not offer.

What does the PolyShield coating do?

PolyShield is a waterproof polyurea finish applied to the plate exterior. It seals the UHMWPE core against moisture penetration and reduces fragmentation risks on impact. The coating contributes to the plate's durability without adding meaningful thickness or weight.

How heavy is a two-plate setup with CaliberHX 10x12 plates?

Two 10x12 CaliberHX plates weigh a combined 2.66 lbs. Paired with a lightweight concealable carrier, a complete front-and-back Level IIIA hard plate setup can come in under 5 lbs total, depending on the carrier selected.

Can this plate be shipped to my state?

The CaliberHX cannot be shipped to New York or Connecticut due to state body armor restrictions. It is also subject to US export regulations — export or transfer outside the United States without proper authorization is prohibited. 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.
