Pros:1. Not too bulky but big enough for the normal high school and college student. Rough estimate of carrying capacity: 3 big yellow phone directories.2. Has 4 compartments, including one for portable music device. All the smaller compartments are easily accessible, which is what most people should want of smaller components.3. Water proof.4. Straps are comfortable.I like this backpack. I've not detected any flaws yet. I usually use it to carry my 15.4 inch laptop + charger, a binder, 1 or 2 books sometimes + my lunch. I bought this backpack for $ 25 at amazon.com. Shame they've increased the price.
