This vintage Osprey 115 liter duffel bag has it all! First, it is from the 2013 BSA National Jamboree. Second, it is HUGE! Third, you can use it as a duffle bag or a backpack. The backpack straps store in a zip compartment at the top. This bag is used and shows some scuffs. All the straps. zippers, velcro and tabs work great. Please see photos.
