18 oz Food Flask is rated 3.0 out of 5 by 2.
Rated 1 out of 5 by from Doesn't keep food hot for more than an hour I have one of these and it doesn't keep the food hot at all. I've even tried pouring boiling water into it and sealing the lid immediately. Within two hours of sitting on my kitchen counter the contents are luke warm. I'm extremely disappointed in this product. I absolutely love my other HydroFlask products, but this was a waste of $35. I wish I could trade it in for some other HydroFlask products.

Rated 5 out of 5 by from Best bottle ever Bought the 18 and the 32 oz one, and it is the best bottle I have ever owned. Put ice in it with water and it kept ice in it for over 30 hours. And it doesnt sweat and make my backpack gross.

Q & A

How long does the food flask keep food hot?

Asked by: Rico
Hi there, You bring up a great question! Our Hydro food flasks keep your food hot for up to 4 hours. Because the food is a thicker content, it takes more energy to keep that temperature consistent. Our products significantly slow down the transfer of energy from either the contents to the environment or vice-versa. The thicker the contents the more energy it will take for the flask to keep this content hot for longer than 4 hours. If, for example, you place lasagna in your flask, it should keep that temperature hot for 4 hours. If you were to place hot soup in a flask, it will stay hot for about 6 hours. Happy Hydrating!

Can you boil water in any of the hydo flasks?

Asked by: solrac
Hello, Thank you for asking, it is not recommended to use a Hydro Flask as any type of boiling device. You can boil water in a tea kettle or kitchen pot and then pour the boiling water into the Hydro Flask. Our flasks are designed to keep your beverage hot for 6 hours and cold for 24 hours. Cheers!

I cannot open my food container with a soup. Why is it stuck? So disappointing.

Asked by: Lola
We have a trick for your stuck lid. Submerge and soak the flask with the cap on in warm water for at least 20 minutes. After that time the lid should come off easily and you should not have the problem again. Please let us know if you have any additional questions, or if this trick does not work.

I think the obvious use for this is liquid foods: soups or chili...but are there any 'outside of the box' type uses?  Just wondering full possibilities on this.

Asked by: BryanB
I washed a pair of socks in the 18oz in an emergency situation.      ......."No", I did not drink the wash water afterwards. least, not all of it.
