Using this backpack is a breeze. First, unzip the main compartment to put in your big items like textbooks and notebooks. You can keep your smaller things such as pens, keys, and your phone in the front compartment's open and cell pockets. For your water bottle or a small umbrella, use the side mesh pockets. When adjusting the shoulder straps, make sure they are at a length that makes you feel comfortable while carrying the backpack. As for maintenance, spot - clean the canvas with a mild detergent and a soft cloth when it gets dirty. Avoid using harsh chemicals as they might damage the material. Also, don't overstuff the backpack to prevent the zippers from getting stuck or the material from stretching out too much.
