This backpack is more like an upright duffel bag than an elongated backpack; the internal Delrin hoop doesn't provide sufficient structural support to keep the bag from sagging when it's upright. There are 3 different haul straps for carrying in addition to the barely adequate duffel bag shoulder strap.
With the aforementioned caveats, this bag is great for travel for a minimalist. It provides plenty of storage space, pockets, and many ways to haul it around (on your back, shoulders,...). The best feature of all is the detachable daypack! It also has plenty of pockets, and the description doesn't mention the two mesh pockets on the side for water bottles!
Because this is a bag that tries to be a backpack, duffel bag, and a travel luggage; it performs adequately for all those functions and definitely not excel in one particular function.
