Brand new US authetic Air Force camo military rucksack. Extremely large and is very versatile. Unfortunately I don't know the actual liters. I got it as a gift from a USAF veteran hoping I'd use it more but was just left in storage.
This model/camo has been discontinued and can no longer be found on official sites!
-metal frame for support
-cushion for comfort and makes carrying heavy things easy
