This backpack is very organized and is in general excellent. The main compartment is large enough to hold 3-4 textbooks, and the laptop sleeve is spacious and sturdy. The secondary compartment has a typical, effective organizer for pens and loose items. The secondary compartment itself is not large enough for letter-sized items, but holds smaller books and loose items well. The third compartment in the their is somewhat redundant to the second, but gives you an additional partition for separating items. To its detriment, the side pockets are not large enough to hold a water bottle; there isn't a good place for that. Calculators, computer peripherals (power cables, headphones, etc) and similar quick access items fit well there. The straps are comfortable, though I'm concerned the fabric component at the base of the straps will break under strain. I'm pleased with the backpack, though I wish it were larger.
