Keep your favorite wine at the perfect serving temperature with this reusable bottle chiller sleeve, designed to fit any standard 750 ml wine bottle. Constructed from pierce-resistant nylon with an adjustable collar, elastic bands, tapered top, and extra bottom support, the sleeve maintains a snug fit across various bottle shapes and sizes. To use, place the sleeve in the freezer for a few hours, then slide it onto the chilled wine bottle and secure with the elastic bands for rapid temperature maintenance. The lightweight, fold-flat design makes it exceptionally easy to store in a kitchen drawer and just as easy to pack for parties, picnics, barbecues, boating trips, and tailgate gatherings. This portable wine insulator works equally well with red wine, white wine, champagne, and beer.
