I bought this pack on a whim (steep and cheap strikes again) and it's been one of my best purchases. I use it as a school backpack, and it does absolutely everything I need it to. The main compartment easily fits a computer, multiple classes worth of books, and still has room to spare for when I feel like throwing in a change of clothes and set of climbing shoes. It's durable, comfortable, and a lovely yellow color. What more could you ask?
