Using this cooler bag is a breeze. First, open the large compartment to put in your wet or dry goods. You can place snacks, drinks, or wet swimsuits inside. For quick - reach items like keys or cards, use the external zip pocket. Put your water bottles in the mesh side sleeves. You can either carry it by the top handles for short trips or wear it as a backpack when you need to be hands - free. When it comes to maintenance, clean it with a mild detergent and a soft cloth. Let it air - dry completely before storing it. Avoid using harsh chemicals or putting it in the dryer. Also, don't overstuff the bag to prevent damage to the fabric or zippers.
