Using this backpack is a breeze. Unzip the main compartment to put in your big items like books or clothes. Slide your laptop into the dedicated sleeve. Use the multiple organization pockets to store small things such as keys, pens, or your phone. When you're on the move, adjust the straps to make sure the padded back panel sits comfortably on your back. As for maintenance, spot - clean the backpack with a mild detergent and a soft cloth when it gets dirty. Avoid machine - washing as it may damage the fabric or the zippers. Keep it away from sharp objects to prevent tears. If you're not using it for a long time, store it in a dry and cool place.
