This handy bottle cooler is perfect for a 1.5-liter wine or champagne bottle. Because the cooler fits snugly around the bottle and can be sealed with the zipper, it remains extra cool. The bottle cooler is made from recycled PET bottles and polyester with an isothermal aluminum interior. You can easily transport your drink and the bottle cooler, thanks to the adjustable shoulder strap. Also ideal for using with a water or soft drink bottle on holiday or at the festival campsite!
