Personal Refreezable Cooler that is four-products-in-one. With the lid off, it',ll (1) hold a 1 liter bottle, (2) a couple cans, (3) will quick chill a bottle of wine in 10-15 minutes, and (4) with the lid and cap screwed on it becomes a high-tech canteen that doesn',t use ice cubes, so drinks are not diluted from melting ice cubes. When quick-chilling wine, you can cycle several bottles through it on a picnic outing. As with the previous Beach Freeze, it can keep a prechilled beverage ice cold up to 8 hours, and make a "room temperature" drink cold in 45-50 minutes. See www.kawabungacoolers.com
