Are you going out for the day, on a trip or just to the beach? Then it's handy to take a cooler bag with you. A cooler bag will keep your drinks, sandwiches and other food cool throughout the day. Cooler bags are cooled by means of cooling elements; for longer periods of time, you will need a cool box or a refrigerator. The advantage of a cooler bag over a cool box is the weight and flexibility of the fabric. The cooler bag is therefore more comfortable to carry and is easy to store.
