  • 18 oz Food Flask is rated 3.3 out of 5 by 23.
    Rated 5 out of 5 by from Love, Love, Love Hydroflask! I love the 18 ounce size because it holds a 12 ounce coke can to keep it cold as well as keeping food either hot or cold. It is the perfect size.

    Rated 5 out of 5 by from Keeps water cold Just bought my 2nd Hydroflask at REI. Paired it with a straw cap and I’ve been drinking cold water ever since. Ice lasts for hours. Great product.

    Rated 5 out of 5 by from keeps smoothie FROZEN I make morning smoothies and like them pretty thick and frozen. this flask keeps my smoothie frozen for several hours. 4 hours for sure! sometimes I'll get to work and get slammed and wont have time for my smoothie until lunch time. no problem, still thick, frozen and delicious! it would be great if Hydro Flask would sell the silicone gasket separately. I keep losing it, it always turns up, but one of these times it wont.

    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 4 out of 5 by from Great features I have 3 bottles and a tumbler. I love how they keep everything cold for so long. I take mine for my errands all day in the heat and it is still cold when I get home. The only thing is I have had to use the warranty 2 times. I have gotten new ones with no problems. The only problem is is when you send it back to get a new one you have to pay for shipping. Which is a lot. $12 to send. That's half the price as I bought it for. That it is not right to me. I don't mind sending it back but I shouldn't have to pay for it. They should let us send it back to the store or send us a postage we can print out and put on the bottle. I'm almost ready to buy something else.

    Rated 3 out of 5 by from it’s good! but i’ve had my food flask for a while and i really like it, it keeps things warm, and overall i’ve never really had a problem in that aspect. i do have a problem with the lid. the screw on lid has a very tiny ring around the inside that goes deep into the lid. it’s so skinny that you can’t really clean it, which results in mold. you can’t put it in the dishwasher, so i’m kind of in a pickle.

    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 The lid gets stuck I bought this food flask about a year ago to keep my daughter’s food to stay warm but unfortunately my daughter is unable to open it because the lid get stuck. I wish this can be replaced. All my flask are good except for this one.

    Rated 1 out of 5 by from Luke warm lunch I've had my food thermos since spring, and use it 2 or 3 times a week. From the time I make my lunch until I eat is about 5 hours. The food is luke warm at best. Ive had a couple other food thermos' and they didnt work either. I bought my daughter one to use for school, and she doesnt mind it being just warm. Expectations can lead to disappointment.

    Rated 1 out of 5 by from Poor product I am a Hydro Flask devotee. Unfortunately this product fell short of my very high expectations of the Hydro Flask products. It DOES NOT hold heat or cold. I have pre-heated and pre-chilled the container with no luck. I have sent a note in to the warranty team in high hopes that they can help. I will never stop using the other products, as they are far superior to anything on the market today (that I have tried).

    Rated 1 out of 5 by from Design flaws I liked old design, these two flasks were used almost daily and didn't last one school year. My local REI store doesn't carry this particular model and I'm hesitant to buy 2 food flasks for my kids for that much money. We own many of the bottles but food containers were the worst product from Hydro Flask.

    Rated 1 out of 5 by from Not a good hydro product I love hydroflasks and own several. I bought this for oatmeal in the morning. I am a teacher and sometimes don't get to breakfast until 9:40 when the kids go to recess and wanted hot oatmeal. I made it piping hot and put into the hydro and about 2-3 hour later it was luke warm. Very disappointing, returned it but still love all my other hydro products.

    I'm interested in getting the food flask for my morning protein shake or for s protein shake snack during the workday. Would this keep the shake cold? if so, for approximately how long? or am i better off with the regular hydro flask for my shakes?

    Asked by: Jez7711
    We do not provide a time frame for the food flasks because it depends on the consistency. Our regular flasks do keep beverages cold for up to 24 hours. With smoothies you should use a deep cleaning method more often. A good one to use is take about a teaspoon of baking soda and some water to make a thick paste. Use a bristled bottle brush to scrub the entire flask thoroughly. Then fill the flask up with boiling water. Leave the cap off the flask. Allow the flask to soak in the baking soda/water mixture until the water inside the flask is cool to the touch. Finally wash and rinse the flask with dish soap and allow it to fully dry.

    Strangely enough I'm not inclined to buy this unless I know (ball park) how long it would keep my meatballs warm for. Can you not give a rough idea?

    Asked by: HorsetoWater
    We do not give a time on the food flasks because it does depend on the consistency. The thicker the item the less time it will keep it hot.
