Using this backpack is easy. Just unzip the main compartment to store your larger items like books or clothes. The internal pocket is great for keeping smaller things organized, like keys or a wallet. The external small zipped pocket is handy for quick - access items such as your phone. Put your water bottle or small accessories in the side mesh pockets. When it comes to wearing, adjust the shoulder straps to a comfortable length. For maintenance, spot - clean the backpack with a mild detergent and a soft cloth when it gets dirty. Avoid machine - washing as it might damage the print and structure. Keep it in a dry place when not in use to prevent mold. Also, don't over - stuff the backpack to avoid stretching the fabric or breaking the zippers.
