As the leading manufacturer of convenient insulated products for over 100 years, Thermos is trusted by consumers to provide innovative portable containers that promote a safe and healthy lifestyle. Thermos delivers when it matters. Thermos brand products offer superior cold retention that keeps beverages cool and delicious for hours, and the 12 oz. FUNtainer straw bottle is no exception.

The result is an insulation layer that performs better than any other. A superior insulated container you can depend on to keep your child?s beverages colder, fresher, longer. This hydration bottle keeps beverages cold up to 12 hours - more than 10 times longer than an ordinary plastic water bottle. Constructed with double wall stainless steel, this 12 oz. straw bottle is virtually unbreakable and built to withstand the demands of everyday use. Featuring a hygienic, push-button lid, this straw bottle is easy to open and drink from. Also included on the lid is an integrated, flip-up carrying loop.

Before you are ready to use, simply empty the water and fill with your favorite beverage. Attaching the lid will further increase the thermal efficiency.
