Using this backpack is a breeze. Just unzip the large double - zipped opening on the main compartment to put in or take out your stuff. The side mesh pockets are great for holding water bottles or small items. When you're wearing it, adjust the shoulder straps to your comfort level. As for maintenance, since it's made of wipe - clean polyester, you can simply use a damp cloth to clean off any dirt or stains. Avoid using harsh chemicals as they might damage the fabric. Also, don't overstuff the backpack to prevent it from losing its shape.
