I'm a teacher, I live in the city, and I commute on public transportation. I can't even explain how much I LOVE this bag. I needed a change from the bulky shoulder bag I've been carting around, and this bag delivered. I almost sent it back without opening it because I bought another bag as well thinking that because the price for this one was relatively cheap it might not be good quality, but this is so awesome I decided to keep both. There's plenty of room for my laptop and the binders I tote back and forth from work, I love the water bottle slots on the side, and I love the variety of pockets. It's completely saved my shoulders from the undistributed weight of the shoulder bag that had me achy, but it's versatile and easy to transition to one shoulder so I have easy access to my bus pass or if I have to take it off my back due to crowded space. I really like the material because it's surprisingly durable and seems like I won't be totally screwed if I get caught walking or waiting for the bus in the rain after forgetting an umbrella (although this is yet to be tested in my case). I also (finally) bought a battery pack since it has the hookup, which has already saved me several times, and I really liked how secure it felt hooking my charger directly to the bag instead of having to fumble around with a phone, battery pack, and bag. All in all, I highly recommend it.
