I misread the description for this - I didn't realize it's a backpack. BUT I use it as a bag and it works anyway. It's really big. I have three BIG school books and a couple of binders and there's room to spare in it vertically and a little down the side. It's exactly what I needed. There aren't any little pockets or anything so I still carry my smaller bag with it (by the same company) but that works fine for me. If I wanted to, I could just put a smaller bag inside it for my phone, glasses, keys etc. Nice, sturdy bag - especially for the price!
