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 cinched. The color is army green. *Please note that the size is an approximate measurement taken in practice. ・Size: Approximately 90cm high x 30cm x 30cm bottom (when packed) ・Capacity: Approximately 80-90L It's easy to close the top. Just align the hole in the hook on the opening with 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 situations 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 some scratches and stains on the surface of the bag. Please check photos 14-17. There may be other overlooked stains. Please purchase only if you understand that this is a used item. Instant purchase is OK. We will ship it in a size appropriate for the product, such as a paper bag or cardboard box.
