The Large First Aid Carrier allows you to carry enough first aid supplies for several people. The unique attachment system allows it to be securely attached to the outside of your backpack and eliminates the annoying swinging and knocking of other hanging kits. It also ensures that the carrier will be readily accessible when an emergency occurs without having to dig through or empty your pack to have access to those supplies. The pack can even be opened and supplies used when the carrier is attached to a pack that someone is still wearing. The light reflective printing on the cover and sides provides greater visibility during low light conditions. These features are packaged in a carrier that weighs only 11 ounces. Unlike prepackaged kits, you get to determine what supplies you will need for your adventure and how you will pack them, thus eliminating paying for unnecessary supplies. While hopefully you will never need medical supplies, it is reassuring that if you do, you will have quick, easy access to them. 200D nylon double ripstop fabric Reflective printing provides visibility during low light conditions Elastic cords and toggles allow secure attachment of kit to outside of backpack Customizable interior allows for a variety of medical gear Elastic loops for pen, penlight and scissor storage Empty interior is ready to be filled with your favorite essentials Capacity 9L / 550 in^3 Dimensions 10" H x 10" W x 5.5" D Weight 11 oz.
