Using this backpack is a breeze. You can put your daily essentials like books, laptops, and clothes in the main zipped compartment. Use the internal pocket for smaller items like keys or cards. The external small zipped pocket is great for quick - access things like your phone or wallet. The side mesh pockets are perfect for holding your water bottle or a small snack. When it comes to cleaning, you can spot - clean it with a mild detergent and a soft cloth. Avoid machine - washing or drying to prevent damage to the print and fabric. Also, don't overstuff the backpack to keep its shape and ensure the straps don't get over - stretched. Store it in a cool, dry place when not in use.
