This is an amazing backpack. I very rarely give 5 stars, but this bag deserves it. At first I thought it was too small. But then when I started putting my necessary things in there I was amazed. It has compartments for everything. Whoever designed this backpack thought of everything. I've had it for a little over a week and I love it. The zippers on the bag are great. You can tell that this bag is made in excellent craftsmanship. I highly recommend purchasing this book bag. This was one of my best purchases in a long time.
