A cylindrical insulator for beer can and beer bottles (it probably also works with other beverages in aluminum cans or glass bottles). Usually made from foam and cloth and sold at convenience stores. But our koozie is made from neoprene which is better than cheap foam or other insulator. koozie can keep beer cold and hand warm at the same time.
Koozies are used to insulate a chilled beverage from warming by conduction and heat radiation, like a hand, warm air, or sunlight. Using a koozie can reduce the rate a drink warms in the sun by up to 50%.
Other uses include easily identifying one’s beverage from another person’s and for marketing. By imprinting on the koozie 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, which generally has a hole at the base to ease inserting and removing beverage containers.
