Remember your uncle's koozie... wrapped around a Hamm's beer while he ate an entire bag of Cool-Ranch Doritos to himself as he sat in his broken-down boat in the driveway? These are not your uncle's beer koozies.
These bad little can holders are outfitted with a locking gasket that doesn't let the cold air escape, keeping your PBR or cola-of-choice nice and cold for a long long time.
They're resistant to rust and corrosion, and you can throw them in the dishwasher. Use this koozie on the hottest days of the year to keep your drinks as cool as you are. Your uncle will be jealous.
