Careful...it's easy to overfill beyond airline luggage weight limits (50lbs). That said, it's got room for everything plus!
Bought two of these for a Safari to Africa where soft sided luggage was mandatory. We found these to be excellent in all regards - one improvement would be some side storage bags against the sidewalls of the interior of the bag, but that's a pretty minor suggestion. Otherwise, they were sturdy, held tons, rolled w/o problems, and had well placed grab handles - for the price, they deliver.
I bought this bag to travel between the states and Europe, and to store my gear in when I'm not away from home. I love the ease of getting to what I need with the separated compartments. *Look out for airline weight guidelines though, because this thing is really easy to overfill.*
I liked this so much I bought another one for my college age daughter who is spending the semester abroad. She loves it too. It is extremely well-balanced, easy to maneuver, and holds a lot in an organized fashion for a duffle-style bag.
