Using this backpack is a breeze. Just unzip the main compartment to store your books, clothes, or other big items. The internal pocket is great for keeping small things organized, like your keys or wallet. Use the external small zipped pocket for quick - access items such as your phone or a snack. The side mesh pockets are perfect for holding your water bottle. When it comes to carrying, adjust the shoulder straps to a comfortable length. Since it has a padded back, you can carry it for a long time without getting too tired. As for maintenance, spot - clean it with a mild detergent and a soft cloth when it gets dirty. Don't machine - wash it as it might damage the print and the fabric. Keep it away from sharp objects to avoid tears. Also, store it in a dry place when not in use to prevent mold or mildew.
