Caliber Armor CaliberHX Level IIIA UHMWPE Hard Armor Speed Plate

***Manufacturer's Estimated Lead Time: Fast Delivery estimated at 1-2 weeks!!

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.

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.

The Bulletproof Zone Promise

When you buy body armor, you're buying your safety. We don't take that lightly. Here's what every order from Bulletproof Zone includes.

1. Authorized dealer of every brand we carry

Every plate, vest, and carrier we ship comes from the manufacturer directly to our warehouse. We don't sell gray-market product, surplus, or returns. That means factory-fresh stock, the full manufacturer warranty, and real after-sale support — the kind only an authorized dealer can offer.

We maintain authorized-dealer relationships with America's leading body armor brands, including Spartan Armor Systems, AR500 Armor, RMA Defense, Shellback Tactical, Caliber Armor, DFNDR Armor, Protection Group Denmark, BulletSafe, BulletBlocker, and over 40 more.

2. Best price, guaranteed

If you find a lower price at another authorized dealer of the same product within six months of your purchase, we'll refund the difference.

Why the "authorized dealer" requirement? Because gray-market and surplus armor may not be genuine, may have a compromised supply chain, and almost never comes with a manufacturer warranty. We won't price-match against products that may not actually protect you.

3. Free fitment consultation

Body armor only protects you if it fits. Email us a photo and your measurements before you order, and one of our specialists will help you size your carrier and plates correctly — at no charge, no obligation.

4. Trusted by thousands of customers

Bulletproof Zone has been a trusted authorized dealer of America's leading body armor manufacturers for over five years. We have over 4,000 verified Trustpilot reviews from real customers across all 50 states.

Price Match Guarantee — Terms

  • You must have purchased the item from our website before requesting the price match.
  • Discounted items and "free with purchase" items are not eligible.
  • The item must be in stock on the competitor's website at the time of your request.
  • The price match is valid for six months from the date of your purchase.
  • The competitor must be an authorized dealer of the product. Auction sites (eBay, Overstock), discounters, and gray-market resellers do not qualify.
  • The competitor must operate an online store. Brick-and-mortar-only retailers do not qualify.
  • Price match applies to the item price plus shipping. Sales tax is excluded.

To request a price match, email us a link to the product on our site and the same product on the competitor's site within six months of purchase. We'll process the refund.
