This backpack is super easy to use. Just unzip the main compartment to store your books, clothes, or other essentials. You can put smaller items like keys or cards in the internal pocket. Use the external small zipped pocket for quick - access items. The side mesh pockets are perfect for holding water bottles or small things you want to grab easily. When it comes to wearing, adjust the shoulder straps to a comfortable length according to your body. As for maintenance, spot - clean the backpack with a mild detergent and a soft cloth when it gets dirty. Don't machine - wash it to avoid damaging the print and the structure. Keep it in a dry place when not in use to prevent mold. And remember, since it's an officially licensed NFL product, take good care of it to show your team spirit for a long time.
