Using this backpack is a breeze. First, adjust the shoulder straps to your comfort level before putting it on. You can use the outside front zip pocket for items you need to access quickly, like your phone or keys. Open the zip - top closure to access the main compartment for larger items. When carrying, you can either use the shoulder straps or the back carrying/hanging loop if you prefer. As for maintenance, spot - clean the soft canvas with a mild detergent and a damp cloth when it gets dirty. Avoid using harsh chemicals as they may damage the canvas. Also, don't overstuff the backpack to prevent stretching the fabric or breaking the zippers.
