This is a German made berghaus rucksack, very heavy duty military backpack. Has a removed metal internal frame comes with hip belt. It has lots of straps and loop holes for attaching gear. It has zippers on both sides of the pack for attaching side pocket, but the pockets are not included. The pockets if you can find them increase the capacity by 20 liters. I used it mostly for ruck hiking it comfortably holds 50 pounds. Has very comfortable shoulder straps.  Thanks for looking
