To use this Incase side bag, simply unzip the compartments to put in your daily essentials like your phone, wallet, or keys. The faux - fur pocket is great for keeping small, valuable items safe. When you're done, zip everything up and carry it on your side. As for maintenance, use a soft, dry cloth to wipe off any dirt. Avoid getting the bag wet as much as possible, especially the faux - fur part. If it gets a little damp, let it air - dry naturally. And be careful not to overstuff the compartments to keep the bag's shape intact.
