Using this backpack is easy. Just unzip the main compartments and start loading your stuff like books, laptops, or clothes. Put your laptop in the internal sleeve for safe storage. When you carry it, adjust the padded shoulder straps to your comfort. As for care, avoid sharp objects that could tear the 600D nylon fabric. If it gets dirty, use a mild detergent and a soft cloth to gently clean it. Don't expose it to extreme heat or sunlight for long periods to maintain the quality of the gloss screen print and the color. And always close the zippers properly to keep your items secure.
