I bought this for my daughter at college. Through highschool, we all used FUL backpacks (different style). She immediately liked the Brickhouse sling style of backpack. It was easy to put over and take down from her shoulder. There was plenty of room for her MAC laptop, all that goes with it, and for books and supplies for a few classes.
The only downside was the weak joint at the end of the sling strap. She said it broke within the first week of use. Her friend and her figured out that a carbiner worked great to replace the broken clip, so all is well. I just think that FUL didn't see that as being a trouble spot for stress.
