18 oz Food Flask is rated 4.428571428571429 out of 5 by 7.
Rated 5 out of 5 by from Food Flask is awesome! I ride my motorcycle to work and dont eat out but love hot food and hate the way microwaved food tastes (yes, I have issues). I pour boiling water into my food flasks while i am cooking my breakfast and lunch in the morning then dump the water, put in the hot food and seal it. Both flasks fit nicely into my backpack next to my hydroflask water bottle and i have a piping hot breakfast, an hour later and five hours after I still have a nice warm lunch. Not right out of the pan hot, but still hot enough to eat without needing to microwave. And my water STILL has ice in it when i get home at night. All in all, Love the products and the green color!

Rated 5 out of 5 by from Motorcycle Adventure Riding - Great Accessory I bought this to take with me on my BMW R1200GS when I go camping. My plan is to put this in the freezer, place my limited perishables in it (half & half for coffee/cooking, butter, precooked crispy bacon, and ice on top). If all works as advertised, I'll have unmelted butter to cook my dinner with that evening, half and half to add to my mac n cheese pasta dish cooked on my JetBoil, unspoiled half and half 24 hours later, for my morning French Press Coffee, *and* crispy bacon to add to my breakfast skillet of rehydrated eggs, sausage, and hash browns. Who said adventure riding/camping had to be without a few creature comforts?? Very cool product... Updated review once I confirm it all works. If it's anything like my 40 oz Hydroflask water bottle, I'll be in good shape. Also, while initially I wasn't wild about the green color, it's actually kind of cool, as it makes it very easy to identify from the rest of my gear.

Rated 5 out of 5 by from Keeps food hot for more than 7 hours! I work in an office, am vegan and do not use microwaves. I love to cook. I cook my lunch around 6 am and eat around Noon. This beauty kept my home-made lunch hot, hot, hot! There is nothing quite like retreating from the business of a job, finding a sunny place outdoors to eat lunch and then being able to open up this adorable, well-designed container and have a hot lunch! I love it and just bought the 12 ounce container so that I can use it for coconut water.

Rated 5 out of 5 by from In love with it! I just bought this yesterday. At 3pm yesterday, I stopped and put some crushed ice and juice in it. I drank about half before I got busy and forgot about it. This morning I grabbed the bottle to head out and there was still crushed ice rattling around in the liquid! The last time I took a drink out of it and there was still ice was at 9 a.m. Amazing! For a person like me that loves water best super cold it's the best purchase I've made in a long time!

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 I love these bottles! I have bought a few of these kinds of bottles from other companies and was not satisfied. then I tried hydroflask, and it was exactly what I was looking for! I love to drink a lot of ice water, and thanks to the wide mouth design, I can use any size ice. and if I dont finish the ice, its still there the next day! I am so happy! what a good product!

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

Will the food Flask keep my food hot if I put it in a lunchbox with other food that require an ice pack? Will this cause the food flask to not keep my food hot at all? or shorten the time it remains hot?

Asked by: dragon411
Yes, the inside of the Food Flask should remain hot. The outside temperature will not affect the inside of the flask.

If I made a semi frozen smoothie bowl and ate it out of the food flask (leaving the lid open the entire time) for 2-3 hours, would it keep the smoothie colder than if I ate it out of a normal bowl?

Asked by: smoothievibes
It should keep it colder than eating out of a regular bowl, however, it won't last as long as if the flask was closed.

The Food Flask is best to use for food, however, it can be used for hot/cold beverages, as well.

Are there pictures of the lid for this 18oz food flask? I can't seem to find any on your website. I want to see how the lid is constructed and whether it has a pressure release valve on the lid. Please show pictures of the lid.

Asked by: DCJD
The lid of the Food Flask is what's shown in the product pictures. It's just a standard screw on/screw off lid.
