This is a large duffel bag used by soldiers to carry their personal belongings when moving. This is a USED item that was actually used. It comes with adjustable shoulder harnesses so it can be carried like a backpack, and it also has carrying handles on the sides so it can be carried horizontally. I have the new type with a center opening, but this early type is much more masculine and definitely cooler. It has a large capacity, so it can get heavy if you put too much in it, making it ideal for carrying large items like sleeping bags, blankets, and changes of clothes. I've attached some example photos. I'm selling this one, which is in good condition among the several I own. Thank you.
