I haven't used the bag yet so I can't comment at all on its' durability. However, it has perhaps even more pockets than it appears to online. I bought it for this reason so I am thrilled. It has a super padded back and the straps seem very comfortable. It looks less wide in real life, but of course I haven't stuffed it full of things yet. It will easily fit the widest of textbooks I have with plenty of room left over. I was hesitant to  buy this without seeing it in person but I could not be more pleased with my decision to get it. It seems to be made of sturdy stuff and aside from slightly difficult zippers (they seem to be opening easier every time I open and shut it) this is perfect for what I wanted it for, long long days at a university.
