The Elite Choice for Severe Hemorrhage Control The SOF® Tactical Tourniquet (SOF®TT) is the preferred life-saving device for many of the world's most experienced special operations units. Selected for its uncompromising reliability and ability to control severe bleeding in the harshest environments, it is the tourniquet trusted to stop the most difficult lower extremity hemorrhages on the battlefield. Unlike competitors that rely on Velcro, the SOF®TT utilizes a high-strength buckling system that performs flawlessly even when soiled, muddy, frozen, or wet. Key Features 100% Effective: Proven to be 100% effective in controlling hemorrhage during rigorous testing by the US Army Institute of Surgical Research. Aircraft Aluminum Handle: The windlass handle is machined from a solid piece of aircraft-grade aluminum, ensuring it maintains strength and integrity in extreme temperatures where plastic might fail. Unified Application: Designed for simplicity under stress, the SOF®TT uses the same application method for both arms and legs. There is no need to learn specific loop routing for different limbs. Weather Resistant: The fastening system eliminates Velcro, which can fail when clogged with mud or ice. The SOF®TT locks securely in any environment. Dual Locking System: Features Dual Locking Rings for a backup security system, plus a Safety Set Screw that prevents accidental release during tactical patient movement. Why It Matters In high-stress combat or rescue scenarios, cognitive function drops. Complex devices lead to failure. The SOF®TT accounts for human performance factors by removing the "multiple choice exam" aspect of application. Whether you are treating a thigh or a bicep, the motion is the same. Its robust construction means it won't snap under the extreme torque needed to occlude a femoral artery, making it the standard for many units specifically for lower extremity bleeds. Technical Overview The tourniquet features a 1.5" strap width for wider compression. It is Made in the USA and carries NSN: 6515-01-530-7015.
