I love this backpack. It holds a ton when at full size and folds down nicely to be more compact when less full. I've used this to travel a lot and it fits well beneath the plane seat in front of you. The side zipper for the laptop compartment is also handy, but can create a crisis if you don't notice it is unzipped, load your laptop from the top of the bag and then pick up the bag - out slides lap top. It also looks really nice on and keeps a slim profile.
