Space, portability, conveniency.
This backpack is a go-to for just about anything. First, packing is made easy with 5 pockets, one of them being huge and roomy, with four smaller pockets for your cell phone, camera, whatever. Also, there's no trouble getting out the door with it. It's very comfortable and easy to get out with. Lastly, the skate strap on the back gives you an extra free hand to high five people with when not ripping on the old shredstick. Convenient? Definitely.
