Abstract: An insulating sleeve for a beverage pitcher is disclosed. The sleeve is a flexible jacket capable of surrounding the pitcher while allowing the pitcher handle to extend out through the side. The jacket also has an open top to permit the pitcher's pour spout to extend out of the top, and an open bottom to permit the base of the pitcher to extend out from the bottom. Advertising messages can be positioned on both the outside and inside of the design, and the sleeve is reversible. The jacket can be formed from a flat piece of material that is generally trapezoidal.
