This bag is sturdy and very roomy.  You can pack quite a few days worth of things in this bag and you can easily go over the airline weight limit if you're not careful.  The great thing about this bag is even if you over pack this bag (or don't want to lug it) you can simply unzip and pull out the handle and roll it around instead.  This bag has been on one trip so far and was fine as the only bag.  I used it for a 5 day 4 night trip and there was ample room for my clothes, shoes, and electronic things.  I even had my laptop in there.  It has a multitude of compartments that are a major benefit to this bag because you can keep so many different things separated  and when you are not using the bag you can flatten it out and slide it under or behind a bed or dresser when not in use.  The handle is the double type and is hidden under a zippered opening.  This bag is nice looking as well as functional.
