The AMP72 40L Backpack has two mesh organizing pockets on the inside of the compartment and an additional small pocket on the bottom of the front[1]. The Osprey Farpoint 40 also has internal compression straps and zippered storage pockets for organization[2]. The G4Free 40L Lightweight Packable Hiking Backpack has a zippered pocket in the main compartment to organize items[3]. The Mission Workshop Fitzroy 40l is aesthetically pleasing but hard to organize due to limited pockets[4].
