  1. 1. Torso Measurement

    • A. Bring your chin to your chest and feel for the most prominent bony bump where the slope of your shoulders meets the back of your neck. This is your C7 vertebra and the top of your torso measurement.

    • B. On each side of your body, feel for the top of your hip bones, just below the sides of your ribs. With fingers pointing forward and thumbs pointing backward, draw an imaginary line between your thumbs. This is the bottom of your torso measurement.

    • C. Stand up straight and ask a friend to measure the distance between your C7 vertebra and the imaginary line between your thumbs using a flexible measuring tape. That’s your torso measurement. If you are between pack sizes, go with the smaller size.

  2. 2. Hip Measurement

    Although your torso measurement is the best indicator of your pack size, it’s still important to check your hip size when using a hipbelt. To find your hip measurement, wrap a flexible tape measure around the top of your hip bones, just below the sides of your ribs. This measurement is slightly higher than your waistline

Rated 5 out of 5 by from Perfect for SOUP! I love my food flask. It keeps my soup hot all day long.

Rated 5 out of 5 by from Stays SUPER hot!! I put hot water in this overnight, dump it in the morning and put in my heated up lunch to take on the road. It’s not just warm when I get around to eating it, it stays hot! Bonus points for sealing like a champ and not leaking when I chuck it in my bag. I love this thing!

Rated 5 out of 5 by from Keeps food warm all day! I got tired of getting to lunch and having my soup be cold... well this lovely food flask has changed my life! I now get to lunch and my soup is like I just pulled it out of the microwave! I would highly recommend!

Rated 5 out of 5 by from Great For Packing Lunch I bought this to bring food in for work, and I usually put granola and yogurt in it. It's always cold when I get to it which can be a bit into the day sometimes. It also cleans really well, although if I were to do it over I would probably go for the smaller size as this big one I end up leaving empty space.

Rated 5 out of 5 by from Very impressed! I have been using this flask for about a month and I have no complaints. Unfortunately at my children’s school they do not have any microwaves to heat up food and this flask keeps food hot until lunch time.

Rated 5 out of 5 by from keep the liquid hot I like it because it keeps the coffee and tea hot .I like that I can able to bring it to work and I'm surprise that even during noon time when I open the lid my coffee or tea still warm. I also love the color and how easy it is to open the lid opening can be a cup.

Rated 5 out of 5 by from Love! Bought this for my husband. He works 12 hour shifts and doesn't have a break room to heat things up. I put soups, pasta and food with any type of sauce in this for him and 5 1/2 hours later for his lunch it's still hot/warm depending on what we put in it! This thermos is a life saver and gives my husband an opportunity to have a hot lunch everyday instead of just a cold sandwich.

Rated 5 out of 5 by from Truly Maintains Temperatures for hours! There is a reason Hydro Flask products are so popular..... the quality is amazing! I am currently doing a juice/ liquid diet (juice, smoothies, blended soups etc...), and a big challenge for me has been being able to have my liquid meals away from home. This food container has been a huge solution for me. Even hours after putting soup in the flask it is still very warm and does not need any additional heating. I have also found smoothies to stay chilled for a long time. It far surpasses any food container I have ever used when it comes to maintaining temperatures for long periods. My flask is a pretty blue, and has a sleek attractive design. It has a screw-top lid, and I have not had any problems with leaking. It is the perfect size for about a bowl worth of soup, but of course this would also work great for storing many kinds of food you would like to keep warm (or chilled). I truly am thrilled with this product and will be putting it to a lot of use.

Rated 5 out of 5 by from Good This hydro food flask is amazing my husband takes it to work and he says when it’s lunch time his food is still really hot as if he had barely heat it up in the microwave. I have also used it myself on drinks and it keeps them fresh for a lot of hours, i take it with me when i go out because my kids are always thirsty and this is a big help because when i give it to them the drink is fresh.

Rated 5 out of 5 by from Works great My daughter loves hydro flasks and uses her water bottle every day. So I decided to get this food one for her, and I'm glad I did. She can put ice in it in the morning before school and there will still be ice later that night. She brings soup or noodles (like ramen) to school and at lunch time, it's still warm. So this definitely does what it claims to do. It's great for bringing on long car rides and camping too. I'm glad I got this, and I'm thinking of getting more so we can each have one. It's made well and it'll last a long time.

Rated 5 out of 5 by from Great product! I received this hydro flask recently. I love the size. I was presently surprised as it holds plenty and it does a great job maintaining the temperature of the food! I would recommend this product to a friend.

Rated 5 out of 5 by from Blue Pill Received this cool looking flask and I gotta say I like it. I use it for Water and it keeps it cold like it should. One day I had left it in my car for 8 hours and when I opened up to take a drink of water it was still super cold!! It sold me i use it every day now. I call it the Blue Pill since it looks like one. Great Flask and im happy with it.

Rated 5 out of 5 by from Performs Well Hydro Flask makes a great product, and the 18 oz Food Flask is no exception. The screw on lid makes a tight seal, so nothing spills out. Perfect for soups, stews, beverages, or other liquids whether hot or cold. I've used it to take lunches to work as well as to bring milk for my morning cereal while on-the-go. It also works great in-home as a storage container for the fridge.

Rated 5 out of 5 by from Great for hiking and camping My husband is an avid camper and often goes on hikes during his trips. So, this was great for him. Great size to hold hot soup, or oatmeal or something cold like a smoothie. It’s sturdy and has a great seal and lid.

Rated 5 out of 5 by from Great I got this for this weather so me or my husband can take leftovers or snacks to work with us. I love it. It's perfect for fluids or any kinda snack you want cold or warm. Thinking about getting couple more.

Rated 5 out of 5 by from Obsessed My girls and I are obsessed with Hydro Flasks and this hot and cold food flask is a great edition to our collection. Absolutely love the shade this shade of blue. Keep all food items to the perfect temperature. Such great quality. Highly recommend to everyone.
Date published: 2019-10-01
Rated 5 out of 5 by from Works great!! I love this product! It’s big enough to hold a full meal and keeps it hot or cold for a really long time - like a full day! The container is insulated and doesn’t sweat, and the lid has an inner seal to prevent leaks. I love the bright blue color too. Its fairly heavy when full but could easily be packed in a lunchbox or bag. I also like that the material doesn’t leach chemicals into food. The only drawback of this product is that is has to be handwashed. I’d love to have a smaller version as well for snacks! The slightly rough texture of the outside of the bottle makes it easier to grip to unscrew the lid. Overall, great product from hydro flask!

Questions

My hydro Flask has been my favorite thermos for several years but now the lid won&rsquo;t open without a terrible struggle. &nbsp;The lid turns and makes clicking noises but someone stronger than me has to work it loose. &nbsp;Do I need to replace the seal insert?

Asked by: Gillian79
This is caused by a vacuum in the flask. If you are still having issues we can replace it under warranty. We don't carry gaskets and we are out of lids replacements. https://www.hydroflask.com/frequently-asked-questions#product_warranty

I saw a video where some people put a whole container of Ben and Jerry&rsquo;s ice cream in the food &ldquo;flask&rdquo; (the pint ice cream) and took out later for enjoyment. Is that your food flask and if so, which size? We own 6 32oz Hydro Flasks and we love them.&nbsp;

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.
