This bag is the pinacle
"Used it for a 7 day trip both as an airport bag and a hiking backpack. All the straps are very comfy. The thing does it all. Surprisingly spacious interior that fits under the seat on an airplane. (Yes, it sticks out a bit, but I've never had anyone complain)! A European budget airline would NOT allow that, but any US carrier will. Only piece that is a little funny is the smallest zipper pockets. Kind of hard to get your hand into. Other than that, it's awesome"
