Thermos Icon Kids Water Bottle 18oz vs Owala FreeSip Kids Bottle

Both are insulated stainless kids bottles with leak-proof lids, so the choice comes down to capacity and drinking style. The Thermos Icon holds 18oz, keeps drinks cold up to 16 hours, has a wide mouth for ice and cleaning, and a Griptec base that stays put on a desk. The Owala FreeSip holds 16oz and its patented spout lets a kid sip through the straw or tip it back to swig, which owners of the adult version praise. Pick the Thermos for more volume and easier filling; pick the Owala for the two-way spout.

  • Choose the Thermos Icon if you want the larger 18oz bottle, a wide mouth for ice and scrubbing, and a non-slip base for a kid who sets the bottle down hard.
  • Choose the Owala FreeSip if your kid switches between straw sipping and tipping the bottle back, and you want the smaller 16oz size for small hands and cup holders.

What reviewers say

Thermos Icon Kids Water Bottle 18oz

Owners of Thermos kids bottles generally report the insulation and leak-proof lids hold up to daily school use, and the straw design is easy for young kids. Common complaints center on the straw parts wearing or being fiddly to clean, and on capacity being small for bigger kids.

What people mention
  • Cold retentionPraisedOwners say drinks stay cold through a full school day without ice.
  • Leak-proof lidPraisedParents report the closed straw lid doesn't leak in backpacks.
  • Straw durabilityMixedSome say the straw works well for kids but the soft parts wear or need replacing.
  • CleaningMixedThe wide mouth helps, but straw and lid parts take more effort to clean than a simple cap.

Questions and answers

Which is better for a younger kid?
The Owala FreeSip, because the 16oz size and slim body are easier for small hands to hold and carry. The Thermos is the better pick once a kid drinks more and needs the extra capacity.
Which keeps water colder longer?
Thermos states up to 16 hours of cold retention with no ice needed. Owala uses triple-layer insulation but does not publish an hours figure, so the Thermos has the clearer claim.
Can both go in a backpack without leaking?
Yes. Both lids are leak-proof when closed. The Thermos straw lid is designed to stay sealed in a bag, and the Owala flip-top lid locks shut the same way.
Is the Owala worth stepping up to over the Thermos?
Step up to the Owala if the two-way FreeSip spout and the lifetime warranty matter more than capacity. Otherwise the Thermos gives you more volume and a wider mouth for less fuss.
Which is easier to clean?
The Thermos, with its wide mouth and top-rack dishwasher-safe body. The Owala's straw and flip lid have more small parts and are best hand washed.
Do both fit in a lunch bag?
The Thermos is 8.3 inches tall and 3.2 inches wide; the Owala is 8.84 inches tall and 2.85 inches wide. The Owala is slimmer, so it slides into narrow pockets more easily.
