Koozies

Koozies are insulating sleeves for drinking containers. They are designed to keep beverages cold and to reduce condensation, improving grip and comfort. They are commonly used with cans and bottles, and can be found at sports venues, parties, and outdoor events.

Materials and design: Most koozies are made from polyurethane foam or other foam materials, neoprene, or fabric with a foam core. The sleeve stretches to fit standard containers and creates a barrier between the container and the hand, slowing heat transfer and reducing condensation.

Sizes and customization: The most common size fits a standard 12-ounce can, with versions for 16-ounce or tallboy cans and for bottles. There are slim or compact versions for slim cans. Many koozies are decorated with logos, team colors, slogans, or photographs and are used for branding, gifts, or personal expression.

Care and maintenance: Foam koozies are typically hand washed with mild detergent and air dried. Neoprene variants may be machine washable or hand washed, depending on the product. Avoid high heat, which can damage materials.

Trademark and usage notes: The term koozie originated as a brand name and has become a generic term for insulated drink sleeves. Some products are marketed as can coolers, beer cozies, or drink sleeves. Availability and designs vary by region and retailer.

Environmental considerations: Reusable koozies can reduce waste compared with disposable cups and napkins. Durability and recycling options vary by material; neoprene is recyclable through some programs, while foam is less commonly recycled and disposal should follow local guidelines.
