I bought one of these backpacks, and it met all my expectations.  I was going to buy a rolling duffle bag, but I gave this a try.  I thought there wouldn't be enough room for my weekend trips where I pack for myself, my wife and my little girl, well there is.  I recently took this to Vegas and we were able just to take this bag.  I would recommend this to anyone on weekend trips or week long trips by yourself.
