Camo Coozie with Camo Vibrator

A Beer Koozie

A beer koozie (see other names below) is a fabric or foam device that is designed to thermally insulate a beverage can or bottle.The primary use of a beer koozie is to effectively insulate a beverage from heat via both conduction and external infrared sources (for example: a hand, warm air, or strong sunlight)

Using a beer koozie can reduce the rate a drink warms in the sun by up to 50%. A secondary use of a beer koozie is to easily identify one's beverage from another and for marketing. Many different companies have used the koozie as a promotional giveaway because it is not only inexpensive to manufacture, but its frequent use is more likely to bring the company's name to a household presence. Originally a logo or image was screen-printed on a round foam cylinder with a foam base (generally a hole is provided in the base to alleviate creation of a vacuum). A koozie can be made from many materials like neoprene, polyester, or open cell foam. The Camo Vibrator is the world’s first beer koozie with a hidden vibrator pocket.

The beer koozie has evolved in both material and style. The materials of which the beer koozie has been made include plain foam, neoprene, closed cell foam, and EVA foam. Some companies create koozies for 40 oz. bottles; others adjust to fit the wide variety of sizes of beverage container. The material used to construct the koozie is designed to insulate the enclosed beverage from external sources of radiant and conducted heat (i.e. heat from a hand/or the sun).
