Our koozies are crafted from excellent quality 3mm neoprene in lots of cute patterns. They come in four different styles to keep your favorite beverage cool. Select your style - can, slim can, beer bottle, or water bottle. Can koozies fit most 12 oz. cans and some bottles. Slim can koozies are perfectly sized for 12 oz. Redbull and Michelob Ultra. Beer bottle koozies have zippers and are sized just right for any regular beer bottle. Our water bottle koozies have a strap sewn on and fit practically any water bottle; you can even squeeze them over a Gatorade bottle.
