Name, origin, and trademark dispute
The name "Koozie" is a coined, trademarked term. With a rich heritage in the promotional products industry, the KOOZIE® brand is recognized as a leader in promotional can coolers and cooler bags of all styles and sizes. The KOOZIE® brand first started with the Radio Cap Corporation (RCC). RCC specialized in baseball caps. RCC registered a trademark for the name KOOZIE in 1980 and they first introduced the styrofoam can cooler that we know to this day in 1982. As the promotional product industry grew, so did the KOOZIE® brand adding more to their product line, including drinkware, more styles of can coolers, cooler bags, outdoor leisure items, travel accessories accessories and business accessories.
Norwood Promotional Products acquired RCC in 1991 and continued to grow the KOOZIE® line of products. In 2009, BIC Graphic purchased Norwood and its sub-brands. BIC Graphic dropped the “RCC” in favor of the streamlined KOOZIE® brand name and has since reinvigorated the brand, expanding the line to include even more styles of can coolers, cooler bags and totes, as well as housewares.
KOOZIE® products are made with quality materials and water resistant construction, offering something suitable for each and every special event and budget. Ideal for your next fundraiser, employee appreciation week, company picnic or way to show team spirit, KOOZIE® brand products will be used again and again, providing a lasting reminder of your message.

Other alternate names for can coolers are:
- "beer hugger"
- "beer huggie"
- "beer rubber" 
- "beer sleeve"
- "bottle jacket"
- "can cooler"
- "candom"
- "coastie"
- "kolder holder"
- "drink sheath"
- "insulated can holder"
- "lovely pupper"
- "stubby cooler"
- "stubby holder"
- "tin can tauntaun"
In Australia, the beverage insulator is called a "stubby holder" because local beer was traditionally sold in 375 mL (13.2 imp fl oz; 12.7 US fl oz) bottles colloquially known as "stubbies" due to their short, squat appearance in comparison to the alternative packaging of 750 mL (26 imp fl oz; 25 US fl oz) bottles ("king brown", "tallie", or simply "bottle"), and the 300 to 375 mL (10.6 to 13.2 imp fl oz; 10.1 to 12.7 US fl oz) longneck bottles commonly used for beer imported from North America and Europe. Most Australian domestic beers have now adopted longneck bottles and/or aluminium cans ("tinnies") for their 375 mL (13.2 imp fl oz; 12.7 US fl oz) packaging, and 750 mL (26 imp fl oz; 25 US fl oz) bottles are now sold much less commonly than was the case historically. Victoria Bitter (VB) is notable for continuing to use the traditional stubby, albeit with a twist top replacing the traditional crown seal.
Norwood was in a dispute, on-and-off over several years in the 2000s, over the Koozie trademark status with an online retail business called Kustom Koozies. 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. Kustom Koozies asserted in 2005 that the trademark had become generic. In the years since, Norwood and Kustom Koozies came to a licensing agreement over the use of the trademark, but by 2009 they were in dispute again, as Kustom Koozies tried and failed to cancel the trademark licensing agreement in response to Norwood instructing it to make certain changes to its website, one of which was that "Koozie" should be set out in all-capital letters as "KOOZIE," and another being that the registered trademark symbol "®" be used to identify genuine Norwood KOOZIES.
Koozies are used to insulate a chilled beverage from warming by conduction and heat radiation, like a hand, warm air, warm surface, or sunlight. Using a koozie can reduce the rate a drink warms in the sun by up to 50%.
Secondary 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.
Materials and styles
The koozie has evolved in both material and style. Materials used include leather, neoprene, EVA, polyester, vinyl, and various open-cell and closed-cell foams. There are koozies for 40 oz. bottles, and adjustable koozies that fit different beverage container sizes.
Multiple koozies linked together have increased in popularity, giving the wearer a Rambo type look. The Bandie is such an example that allows the wearer to carry multiple cans in individually insulated koozies.
