I bought this bag for my niece and she loves it. She uses it as a school bag and for overnight trips. It seems to be holding up well. I searched for the right seller as there are so many fakes out there! This is the real deal!
I did like this backpack however the color in some areas seems to be less vibrant then others and their are a couple lighter spots. I would suggest instead of ordering off amazon to go to a urban outfitters or store that sells them and pay 10-20$ extra to receive a good product.
You can fit your book bags in here, but not too much. Just looks awkward and boxy when it's full. Downside is that after a few months, the inside of the bag is starting to come apart and the fabric of the bag is becoming iffy. For the most part, really nice and has an aesthetic touch.
