A collapsible insulated jacket for a beverage container is formed from the same material as that of the carton in which the beverages are sold. A plurality of insulated jackets are secured together along a perforated line. The plurality of insulated jackets can be formed as a portion of the carton or as a separate item removable secured to the carton. A layer of insulating material can be added to the material of the jacket to provide additional insulating properties for the jacket.
