The humble koozie—also known as a can cooler, stubby holder, beer cozy, or drink sleeve—has become an indispensable companion for anyone who enjoys a cold beverage. What started as a simple foam sleeve has evolved into a diverse marketplace offering hundreds of variations in materials, designs, shapes, and functionality. This comprehensive guide explores every aspect of koozies available today, from traditional foam designs to cutting-edge vacuum-insulated models.

What Is a Koozie?
A koozie is an insulating sleeve designed to fit around beverage containers such as cans, bottles, or cups. Its primary functions are to:
Maintain beverage temperature by slowing heat transfer from the environment
Reduce condensation on the outside of containers
Provide a comfortable grip and protect hands from temperature extremes
Serve as a customizable branding surface for events and promotions
The term "Koozie" is actually a trademarked brand name that has become genericized, much like "Thermos" or "Kleenex." The product was first patented in 1981 by Bonnie McGough, who initially suggested goose down as the insulating material before manufacturers moved to foam and neoprene.
How Koozies Work: The Science of Insulation
Koozies keep beverages cold through multiple mechanisms:
1. Thermal Insulation
Materials like foam, neoprene, and stainless steel have low thermal conductivity (ranging from 0.033 to 0.054 W/m·K), creating a barrier that slows heat transfer from warm air to cold beverages.
2. Condensation Prevention
Without insulation, moisture in the air condenses on cold cans, releasing latent heat that rapidly warms the drink. Koozies prevent this condensation, which research from the University of Washington identifies as one of the biggest factors in warming drinks.
3. Hand Heat Reduction
By creating a barrier between your hand and the container, koozies minimize conduction of body heat to your beverage.
Performance Metrics
Scientific testing reveals impressive results:
A 12 oz can without a koozie can warm from 1°C to 10°C in approximately 15 minutes on a 30°C (86°F) day
With a neoprene koozie, the same temperature change takes 45+ minutes—three times longer
A 4mm neoprene koozie can extend a beverage's chill time from 25 minutes (unwrapped) to 60 minutes—a 240% improvement
Stainless steel vacuum-insulated koozies can maintain cold temperatures for up to 24 hours
