To use this backpack, simply unzip the main compartment to put in your books, notebooks, and other big items. The front compartment is great for storing smaller things like your phone, pens, and keys. You can keep water bottles or umbrellas in the side mesh pockets. When adjusting the shoulder straps, make sure they're at a length that feels comfortable on your shoulders. For maintenance, you can spot - clean the canvas with a mild detergent and a soft cloth when it gets dirty. Avoid overstuffing the backpack to prevent damage to the zippers and fabric. And remember, don't expose it to extreme heat or sharp objects.
