Are Owala bottles freezer safe?Updated 2 years ago

Stainless Steel: We’re assuming that if you want to freeze your bottle, it’s because you want your liquids to be cold. But here’s the thing: our stainless-steel bottles are triple-layer insulated, which means that the liquids are insulated from the temperature outside of the bottle. So while yes, the bottle is technically freezer safe, we just recommend putting a few ice cubes in the bottle instead.

Eastman Tritan™ plastic:
We do not recommend freezing plastic Owala bottles. Like most plastic bottles, ours may become brittle and more susceptible to cracking or breaking when frozen. If you decide to ignore our wisdom and choose to freeze the contents, at least make sure you leave room at the top, and the lid open, as contents will expand. (That’s elementary-school science).
