These U.S. Military Surplus EMT Transport Bags are perfect for building custom First Aid kits. The outer construction is a Tight Weave Canvas fabric surrounded by heavy-duty YKK Zippers so what you put in, stays in. Choose your bag by the color and printing on the outside which makes for easy identification. Inside, individual see-through pockets will hold a variety of bandages, gauze, burn gel dressing, alcohol swabs, analgesics and much more. They double as excellent travel bags to hold toiletries and each one uses a heavy-duty spring lock metal hook for hanging up when unrolled.
