Category: Baby > Kids' water bottle. Updated 2026-10-08. Based on 119 counted first-hand reports from Target shopper reviews, Aug 2023 to Sep 2026.

**Question:** Which kids water bottle keeps water cold?

**Short answer:** Thermos Funtainer 12oz Water Bottle has the best record for keeping water cold: 34 of 35 parents said the water stayed cold through the school day or longer. The gaps are small: Owala Kids FreeSip Water Bottle follows at 33 of 35 and Thermos Funtainer Kids Water Bottle has the weakest record here at 30 of 34, which is still a solid result. Leaks and straw problems are a better way to choose than cold alone, and each bottle rests on a small group of reviewers who gave an outcome.

**What stands out:** Praise for keeping water cold runs from 75% to 85% of reviews on all three bottles, so the difference is in the complaints. 22% of reviews for the smaller Funtainer and 12% for the larger one mention leaks, while no complaint shows up more than once for the Owala.

Leaks are the main complaint on both: 22% of reviews for the smaller Thermos Funtainer 12oz Water Bottle and 12% for the larger Thermos Funtainer Kids Water Bottle. Check the straw and any valve for wear or cracks, replace worn parts, and clean them the way the maker says.
