What Is a Koozie?
A Koozie is a brand name for an insulated beverage holder designed to keep drinks cold (or hot) for longer periods. It’s most commonly used for cans and bottles, especially sodas, beers, and energy drinks.
🔍 How Koozie Works
A Koozie is usually made from:
- Neoprene
- Foam
- Fabric insulation
These materials reduce heat transfer from your hand to the drink and slow down temperature changes. The result? Your beverage stays colder, longer—and your hand stays dry.
🏢 Origin of the Term “Koozie”
- Koozie® is a registered trademark
- Owned by Scribe OpCo, Inc. (formerly connected with Radio Cap Corporation)
- First trademarked in the 1980s
Because it was one of the first popular insulated drink sleeves, the brand name “Koozie” became widely used—similar to how people say “Kleenex” for tissues.
📍 Where You’ll See Koozies
- Promotional giveaways
- Corporate branding merchandise
- Sports events
- Weddings and parties
- Bars and festivals
👉 Important note: Technically, only products from the trademark holder should be called Koozie—but in everyday language, people use it generically.
In short:
Koozie = A trademarked brand of insulated drink holder
