Made from a thick neoprene like that you would find on a wetsuit, each koozie drink holder is sized to fit a 12 oz. can with a koozie on it. They have a little stretch to them to fit many medium size tumblers and other similarly sized drinks. They have an adjustable nylon strap with clip to fit around the rim of your Sunchill. They also fit the Megachill & Partychill.
