• Featuring NAR's signature Red Tip Technology® elliptical tab providing added visual clues during application

Noted as the best prehospital tourniquet in the February 2008 supplement of The Journal of Trauma The patented C-A-T® is a true one-handed tourniquet proven to be 100% effective by the U.S. Army’s Institute of Surgical Research. Tests proved that the CAT completely occluded blood flow of an extremity in the event of a traumatic wound with significant hemorrhage.The Gen 7 CAT utilizes a durable windlass system with a patented free-moving internal band providing true circumferential pressure to the extremity. Once adequately tightened, bleeding will cease and the windlass is locked into place. A hook and loop windlass retention strap is then applied, securing the windlass to maintain pressure during casualty evacuation. The patented Combat Application Tourniquet® (C-A-T®) featuring the proprietary red tip design and the mechanical advantage of a band within a band has been the Official Tourniquet of the U.S. Army since 2005.
