Using this backpack is a breeze. Unzip the main compartment to store your textbooks, notebooks, and other big items. The front zip compartment is great for small things like your phone, keys, or a wallet. Just put your phone in the cell pocket and other small stuff in the open pockets. The side mesh pockets are perfect for holding a water bottle or a small umbrella. When it comes to wearing, adjust the shoulder straps to a comfortable length so it sits well on your back. As for maintenance, spot - clean the canvas with a mild detergent and a soft cloth if it gets dirty. Avoid over - stuffing the backpack to prevent damage to the zippers and the canvas. And remember, don't leave it in direct sunlight for too long as it may fade the color.
