When to Choose Combat Gauze XL

• Large Penetrating Wound Cavities — When a standard 3" gauze roll is insufficient to fill the wound volume — high-velocity GSWs, blast injuries, and large shrapnel tracks.
• Junctional & High-Output Hemorrhage — Groin, axilla, and neck bleeds where the wider 4" format provides faster fill and better contact pressure against major vessels.
• Military Medic & Combat Life Saver Kits — For DoD-standard kit builds requiring the NSN-listed, DAPA-approved hemostatic dressing.
• Trauma Team Pre-Hospital Packs — Flight medics carrying extended-range trauma kits where a single oversized dressing can handle the worst-case wound.

Combat Gauze XL vs. Alternatives

• vs. Combat Gauze LE (Standard 3"×4yd) — XL is 4" wide and double-ply, providing roughly double the fill volume per roll. Choose LE for standard IFAK builds; XL when wound volume demands more hemostatic material.
• vs. CELOX Rapid (3"×5ft) — Combat Gauze XL relies on kaolin to activate the patient’s own clotting cascade; CELOX Rapid’s chitosan works independently of coagulation status. XL is the DoD first-line recommendation; CELOX Rapid is preferred in anticoagulated patients.
• vs. Chitogauze XR Pro — Both are kaolin-based, but Combat Gauze XL has the established NSN, DAPA listing, and direct CoTCCC first-line recommendation.

Frequently Asked Questions

What makes the XL version different from standard Combat Gauze?

Combat Gauze XL is 4 inches wide versus 3 inches, and features a 2-ply double-layer construction. This delivers more hemostatic surface area and absorptive capacity per roll — designed for large wound cavities, junctional bleeds, and high-output hemorrhage.

Is Combat Gauze XL the same as the DoD military-issue product?

Yes. Combat Gauze XL carries NSN 6510-01-600-4705 and is listed on DAPA, confirming it as a DoD-procured item and the CoTCCC-recommended hemostatic dressing of choice for the U.S. Department of Defense.

Does kaolin generate heat when it contacts blood?

No. Kaolin is an inorganic mineral that is chemically inactive. It does not generate heat, contains no animal or human proteins, and does not cause botanical reactions. It works by activating Factor XII in the coagulation cascade.

How much pressure time is required with Combat Gauze XL?

Apply firm, direct pressure for a minimum of 3 minutes after wound packing. For arterial bleeds, maintain pressure until transport to definitive care. Do not remove packed gauze in the field once a clot has formed.
