Using this men's RVCA cooler bag is easy. First, open the bag and place your cold items inside. You can use the adjustable shoulder strap to carry it on your shoulder for long - distance trips or hold it by the carry handle for short - term use. The mesh side pockets are great for storing small items like keys or a phone. When it comes to cleaning, simply wipe the inside and outside of the bag with a damp cloth. Avoid using harsh chemicals as they may damage the insulation. Also, make sure to dry the bag completely before storing it to prevent mold growth.
