Gourmet on the go.

After a few hours navigating rapids, hitting the slopes, or corralling kiddos, you’ll be happy to see that what you put inside our 18 oz Food Flask is still as piping hot or ice cold as when you packed it. From hot soups to frozen smoothies, it keeps your favorite foods at the perfect temperature. And professional-grade stainless steel means it won’t retain or transfer flavors. Nobody wants this afternoon’s protein shake to taste like last week’s coconut curry.

Rated 5 out of 5 by from #ThemGains This product is great if you are into food prepping for a long day at school/office and helps get those gains from working out and keeps you consistent. I put noodles and chicken in it and 3 hours later it was still very hot. I'm sure it will stay hot even longer.

Rated 5 out of 5 by from Stylish, keeps food hot I bought this from REI to take soup with me for jury duty. The trick is to get the soup super hot and fill the container to the top. It was literally so hot four hours later that it burned my mouth. Love Hydro Flask. My third product. All ROCK

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 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 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 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 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 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.

Rated 2 out of 5 by from Love My other Hydro Flask products, not this one I own several Hydro Flask bottles and the pint glasses and LOVE all of them, so when I wanted to take soup to work with me, I was sure Hydro Flask would have the best product, plus I love the colors and style. My soup is barely warm when lunch comes around. I'm very disappointed with the lack of heat holding. I have tried pouring boiling water in ahead of time and tried getting my soup super hot before putting it in the container, but it is still lukewarm 3 hours later.

Rated 1 out of 5 by from Hot?? NOT!! I bought this in June, but have only used it twice. Both times I boiled water to warm it up first, cooked my soup until it was pipping hot and both times, 6 hours later my soup was ice cold. I am super disappointed because my 40oz hydration bottle that I bought over a year ago has been keeping my water ice cold so I naturally assumed the food flask would be as awesome.

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.

Q & A

Is it dishwasher safe?

Asked by: Kitboy
We do not suggest putting your flask through the dish washer. For cleaning, we recommend hand washing with a bottle brush and mild dish soap.

Is the seal on this air tight? Currently using a mason jar to store fresh juice. Wondering if this is an air tight seal to keep the juice from oxidizing and also keep it cold. Thanks

Asked by: Jason L
It could work. However, this is not how the product was made to work, so we would not be able to say for sure that it would or would not work.

Is the thermos meant for solid meals? Or only liquid meals like soup?

Asked by: kirb
You can put whatever you would like in the food flask. The thinner the item the longer it would stay hot. The thicker the item is, the less time it would stay hot.

If I fill it with ice. How long before ice is completely melted

Asked by: Jay888
We do not have a time frame for the food flask. It depends on the consistency of the item you are placing in the flask. The thicker the item the harder it is to keep hot/cold. Our standard flasks would keep beverages cold up to 24 hours is what we quote, but for ice it depends on how much you lukewarm beverages you are putting over the ice.

How long would it keep ice cream?  Would like to take icecream for lunch on a hot day.

Asked by: CasJ
We do not really have a time frame on the food flask. The thicker the item the less amount of time it would keep the food hot or cold because of the consistency.

Can I put it in the fridge? Thanks

Asked by: Veselina
You can, but it really is not going to do anything. The beverage will stay cold without the fridge.
