Using this men's RVCA cooler bag is a breeze. Just open it up and put in your food and drinks. The adjustable shoulder strap allows you to carry it comfortably on your shoulder, or you can use the carry handle. When using the mesh side pockets, you can store small items like utensils or keys. For maintenance, clean the bag with a mild soap and water after each use. Don't use abrasive cleaners as they may damage the insulation or the logo. Also, make sure to dry it completely before storing it to prevent mold and mildew. Keep it in a cool, dry place when not in use to extend its lifespan.
