An bendable double-walled insulated drinking straw for use in drinking hot and cold liquids. The insulated drinking straw comprises an inner tubular member that is sealed to an outer tubular insulating member at a sealed section, and that is separated from the inner tubular member at other than the sealed section to provide an air space therebetween. A flexible joint is formed at the sealed section that allows a portion of the straw on one side of the joint to articulate with respect to a portion of the straw on the other side of the joint. The double-walled portion of the straw may be the drinking end of the straw, or the entire straw may be double-walled, except for the sealed section. In one embodiment, an air space is formed between the inner and outer members. In another embodiment, interconnections are formed between the inner and outer members, such as ribs and serpentine members. In other embodiments, insulating material is disposed between the inner and outer members. The inner and outer members may also be sealed at one or more ends.
