Our take on the 12oz FUNtainer Water Bottle

The Thermos FUNtainer is a 12 oz kids' water bottle with double-wall vacuum insulation that keeps drinks cold for up to 12 hours without ice. A push-button lid covers the silicone straw, and an integrated soft-touch handle makes it easy for small hands to carry. It is dishwasher safe on the top rack and built to survive drops and daily roughhousing. Compared with open-cup bottles and thinner plastic straw bottles, it holds cold far longer and takes abuse better, though it is not for hot liquids.
