Using this backpack is a breeze. First, open the main zip - top compartment to store your books, notebooks, and larger items. You can keep your phone, keys, or small gadgets in the front compartment's cell and open pockets. Place your water bottle or umbrella in the side mesh pockets. When adjusting the shoulder straps, make sure they are at a length that feels comfortable on your back so you don't experience any strain. As for maintenance, spot - clean the canvas with a mild detergent and a soft cloth if it gets dirty. Avoid machine - washing to prevent damage to the lining and zippers. Also, try not to overstuff the backpack as it may affect the shape and functionality of the compartments.
