I purchased this backpack for my nephew who is 15 years old. I actually let him choose the color scheme from the ones that were available online and he really liked the blue/black plaid. It's a nice pack with comfortable straps and a good amount of room. I would say you could fit 3-4 classes worth of books in it at a time. It's a medium sized bag. When I was in high school I would have needed a slightly bigger bag but depending on your course load and if you have a locker where you can drop some stuff off between classes this pack would be adequate. My nephew loved the look when it arrived. It also seems durable, not cheep, like it would last a few years. When I asked him how he like the backpack after the first day of school he said he loved it and that all his friends said it was cool too.
