Thermos Funtainer Stainless Steel Water Bottle With Straw

The 12-ounce Thermos Funtainer Stainless Steel Water Bottle With Straw is our favorite kids water bottle because it’s the easiest one to use. Our youngest testers were able to open and close the top on their own, and its button-release cap design keeps grubby fingers off the straw, prevents leaks, and makes the straw less likely to get dirty when the bottle is dropped compared with other bottles we tested.

With only four parts, the Thermos Funtainer is easy for adults to take apart to clean, and the whole thing is safe in the top rack of a dishwasher. The vacuum insulation keeps drinks chilled for up to 12 hours, and the Funtainer usually costs much less than other insulated bottles. Plus, if your straw wears out or becomes too dirty, you can simply purchase a replacement—no need for an entire new bottle.
