MAMMUT Mammut Model Name Unknown - Brand: MAMMUT - Design: Elephant logo - Color: Olive Green and Lime - Material: Nylon - Features: Mesh pockets and adjustable straps Thank you for viewing. Size: Approximately 25L capacity I apologize that I do not know the details as the model name is unknown. It has a moderate amount of wear and tear, but there are no defects such as accidental disassembly, and I think it can still be used. I am selling it at a bargain price because the model name is unknown. Thank you for your consideration.
