Koozie

A koozie ( /ˈkuːzi/ KOO-zee) (US) or stubby holder (Australian) is a fabric or foam sleeve that is designed to thermally insulate a beverage container, like a can or bottle.

The company RCC specialized in baseball caps before registering a trademark for the name KOOZIE in 1980, and subsequently introducing the product as a can cooler in 1982.

As the promotional product industry grew, more products were added to the KOOZIE brand, including drinkware, more styles of can coolers, cooler bags, outdoor leisure items, travel accessories, and business accessories.

Norwood asserts that names such as beer hugger, can cooler, and huggie do not infringe its trademark, but that koozie, coozie, coolie, and cozy do.

Materials used include leather, neoprene, EVA, polyester, vinyl, and various open-cell and closed-cell foams.
