Shop Killer Koozys

A koozy is a fabric or foam sleeve designed to fit tightly around a beverage can or bottle.

Core Functions

• Insulates Drinks: It keeps cold beverages cold by blocking outside heat.
• Protects Hands: It keeps your hands warm and dry by blocking condensation.
• Identifies Drinks: It helps you identify your drink at parties through unique colors or logos.

Common Materials

• Neoprene: Durable, stretchy wetsuit material that offers the best insulation.
• Polyurethane Foam: Lightweight, collapsible, and highly affordable.

Alternate Names

Depending on where you live, a koozy is also called a can cooler, koozie,, beer hugger, cozy, or stubby holder (in Australia).

Yes, scientific testing shows that koozys effectively slow down the heat transfer from ambient warm air and your hands into the beverage. A neoprene sleeve, for instance, can extend a beverage's chill time by up to 240% compared to an unwrapped can in hot conditions

Neoprene: The same material used to make wetsuits. It is highly insulating, water-resistant, durable, and keeps drinks cold the longest (45+ minutes).

Foam (Polyurethane): A lightweight, low-cost option. While it doesn't insulate as long as neoprene, it holds its shape well and is highly affordable for large events

No, most koozys are crafted for specific containers. The most common sizes are:

• Standard 12-ounce cans or bottles.
• Slim 12-ounce cans (for seltzers and energy drinks).
• Tallboy 16-ounce cans

While mostly used in the summer heat to prevent ice-cold cans from warming up, people use them in the winter or during tailgates and BBQ's to prevent their hands from going numb. Because aluminum and glass are highly conductive, a koozy acts as a barrier to keep your hands warm and dry

You can generally clean a neoprene or fabric koozy by hand washing it with warm water and a little dish soap, or by putting them in the washing machine on a gentle cycle. Air drying is highly recommended to preserve their shape and elasticity
