This is a U.S. military nylon duffel bag. I received it from a colleague at work. The bottom is almost a perfect square, 30cm x 30cm. The height is 90cm. The height will be slightly less when the top is tightened. The color is army green. ・Size: Approximately 90cm high x 30cm x 30cm bottom (when packed) ・Capacity: Approximately 80-90L *Please note that the sizes are approximate measurements taken in practice. It's easy to close the top. Just align the hole with the hook on the opening and hook the metal fitting on the end of the strap. When you put things in it, it becomes cylindrical. It can be used as a handbag, and it can also be carried like a backpack, which is convenient. It has a large capacity, so it's sure to be useful for various occasions such as travel, outdoor activities, leisure, camping, as well as for motorcyclists, those who play survival games, and those who fish. When not needed, it can be folded and stored, so it's also recommended to keep it as a spare in a bag or suitcase. It has been cleaned, but there is a general feeling of use. There are scratches and stains on the surface of the bag, and some threads inside are frayed and exposed. (There are no holes) Please check photos 15-20. There may be other overlooked stains. Please purchase only if you understand that this is a used item. Immediate purchase is welcome. We will ship it in a size appropriate for the product, such as a paper bag or cardboard box.
