The SDG 4-in-1 Koozie is designed to keep that drink of yours cold. Just put in a bottle, 16oz slim can, or 12oz can, and you'll be sipping away on a cold drink for along time.
You can also use this as your cup! The Koozie turns into a cup and you have a straw and tumbler lid included.
We've all been out on the back 9 of a round and taken a swig of our slightly too warm drink. It's a bummer.
Instead of having warm drinks, keep them cold with the SDG Koozie. It's 16 ounces of stainless steel with a double wall vacuum to keep your drinks cold.
