About Packit - PackIt is the smartest and simplest way to keep food and drinks cool anywhere. It's a foldable, freezable bag that works just like a refrigerator on the go, continually chilling items for up to 10 hours. The secret is a special freezable gel built into the walls of the bag. Simply store the entire bag in the freezer overnight. Once the bag is frozen, its walls generate waves of cold air that chill your food and drinks from all sides without ever needing external ice packs !
