Using your Vans Old Skool H2O Backpack is a breeze. Start by using the front organizer pocket to keep small items like keys, pens, and cards. You can easily grab them when needed. Put your laptop in the dedicated sleeve; just make sure it's a 15 - inch or smaller one as it's designed to fit most laptops of this size. The side water bottle pocket is perfect for keeping your drink handy. When it comes to maintenance, spot - clean the backpack with a mild detergent and a soft cloth. Avoid machine - washing to keep the fabric and the logo label in good condition. Also, don't overstuff the backpack to prevent any damage to the zippers or the structure. Store it in a cool, dry place when not in use to keep it looking its best.
