Maybe you’re heading off to the beach or into the countryside and you want a nice cold drink when you get there. Or perhaps you’re off camping for a week and want to make sure your milk and other foods stay fresh. That’s when you need a good quality cool bag or cool box. These insulated carriers keep food and drink cooler for longer, but if you drop in a few ice packs or freeze boards, you can stretch out the coolness to a few days. As most camp sites let you re-freeze your packs, use two lots in rotation and you’ll have chilled food for the whole stay. If you’re not far from a power source (even a car lighter socket), you can get a 12V electric cooler box and have constant coolness just like you do at home.
