This Vans Old Skool H2O backpack is super easy to use. Just open the main compartment to put in your books, notebooks, and other school essentials. There are also smaller pockets on the sides and front for storing items like your phone, keys, or a small calculator. When you're on the go, you can use the adjustable shoulder straps to carry it comfortably. As for maintenance, if it gets dirty, you can wipe it down with a damp cloth. Avoid using harsh chemicals as they might damage the waterproof coating. And remember, the water bottle is not included, so you'll need to bring your own.
