Using this backpack is super easy. You can put your daily essentials like books, notebooks, or clothes in the main zipped compartment. Use the internal pocket for small things like keys or cards. The external small zipped pocket is great for quick - access items. Put your water bottle or small gadgets in the side mesh pockets. When it comes to maintenance, spot - clean it with a mild detergent and a soft cloth if it gets dirty. Avoid machine - washing to keep the print and logo in good condition. Also, don't overstuff the backpack to prevent damage to the straps and zippers. Keep it in a dry place when not in use to ensure its longevity.
