The CAT 1 Stop the bleeding kit has an original CAT brand, military style tourniquet that has a windlass rod to provide extra strength and compression. The compressed gauze compress is 4" wide and made of a fluff-dried woven gauze that is soft and absorbent. Compressed into a smaller package that measures 2 5/8 x 2 1/8 inches, so it's easier and more compact to carry and store. This bleeding control kit has the supplies requested by the Stop The Bleed coalition that aims to educate, train and supply bystanders with the tools and information they need to assist when an emergency or active shooter situation occurs. Packed in a resealable plastic bag that measures 5x8 inches. Great addition to your first aid supplies or emergency response kits.
