    Fresh Food

    • Familiarity: I've put it through the wringer

    I love to use this for things like soup. Keeps it hot for hours! Really durable and does its job very well. Perfect for packing lunches for work or camping.


    • Familiarity: I've put it through the wringer

    Using it everyday for morning coffee, made the night before around 10pm, enjoy a warm drink in the morning. Hydroflask makes quality products. Love the wide mouth and 18oz is a great size.
    If you put something in that's boiling and close it, you'll need a pure concentration of strength and will to open it within an hour after, but that's to be expected for any quality insulated product :) I find putting rubber-bands around the lid and body to be very helpful.
    My only critique is superficial; wish they made it in other colors, and they did!

    Works well short term not long term

    • Familiarity: I've used it once or twice and have initial impressions

    Keeps what I want to eat hot which is to be expected. However don't expect that it'll keep things roasting for a long time. Good for heating something up in the morning and taking it to work or making some dinner and going out that evening and enjoying some hot soup while you start gaze.

    No time for a microwave? NO WORRIES!

    • Familiarity: I gave it as a gift but have feedback to share

    If you don't have time to microwave your soup or just plain don't want to use one then look no further! Hydroflask has your back! put your hot food in this thing in the morning and by lunch it will still be piping hot. I got this for my friend that is constantly driving for her job and so this is perfect for her since she typically doesn't have access to microwave or stove to heat her food. She usually eats fast food but now with this she can pack her own and ultimately healthier meals. :)

    Hot food for hours!

    • Familiarity: I've put it through the wringer

    This food canister is PERFECT for those crisp days where all that sounds good is a nice bowl of hot soup. Now you can take it with you and be prepared at all times for when you're hungry! You can bank on your food staying hot for hours once you've put it in the canister. Throw it in your backpack and hike up to a rad spot for a picnic, or even just to work! Love this product.

    Perfect for hot food on the go

    • Familiarity: I've used it several times

    I have the smaller version and use it every winter great for bring hot meals to work and on the go I love the new bigger size going to buy a few more for X-MAS GIFTS

    Hot food lid functional defect

    • Familiarity: I've used it several times

    Same review as the 12 oz I left. bought an 18 oz with the same problem. Can't get the lid off if you put hot food in. Soft gasket and the lid thread design will not get the lid off. There is a suction that develops and the lid just keeps spinning. You need to pry extremely hard to get the lid off with little to grab onto. If you do get the lid off, the gasket gets sucked into the food. Good for cold food, terrible for hot food. Problem every time with hot soup. No soup for you.
    Tried flipping the gasket, tight, loose, same result. Food is hot and cold though. Hydro Flask Customer service is non responsive. they have successful, proven hard gaskets, yet they go with this useless soft gasket design.

    Hydro Flask Insulated Food Flask

    I’m not a fan of storing food in plastic containers, so it’s great that these are pro grade stainless steel, BPA free and feature double walled insulation. Let me say right here that I am a huge fan of the new colors Hydro Flask is putting out, very sharp, appealing, and fun.I’ve used this to take hot food to my son’s soccer game, on a road trip, and a few other times. As a scientific inquiry, I primed it with boiling water, added hot food, and then opened it once an hour on the hour to see how long the food stayed warm enough to eat. In my case, that was 5 hours and even then the food had residual warmth. This is not your typical test, so I suspect that the flask can keep sealed hot food for at least the 6 hours Hydro Flask states. The food flasks come in two sizes and retail for about $30 for the 12 ounce and $35 for the 18 ounce. Hydro Flask does offer a limited lifetime warranty against manufacturer defects, so feel confident in acquiring one of these.

    5 hour product

    • Familiarity: I've put it through the wringer

    I've had my hydroflask 18oz for about a year now and I love it! It's awesome for travel and work. I mainly use mine for work so I can bring in my own meals and save some money.

    I've tested out my food container to see how long the food actually stays hot for and personally my food container lasts up to 5 hours. I was hoping for a little bit more time with the food flask because I have a ton of hydroflask water bottles and travel coffee mugs and the hot and cold temperatures last FOREVER in the beverage containers.

    Hydroflask is impressive. You should definitely grab this and ditch your plastic containers that you have to reheat your meal in the microwave with. Keep your food fresh!

    5 hour product

    Great hot or cold

      Great food jar that will keep things hot for at least 6 hrs if you pre heat it with boiling water. It also works great for salads if you leave it open and empty in the fridge or freezer the night before. If I pre chill the jar it keeps salad fresh for over 5 hours.

      Amazing Containers!

      • Familiarity: I've used it several times

      These containers are a dream come true. I have been eyeing them for about a year and finally took the plunge after hearing all the good reviews from friends and co-workers. They regulate food temperatures perfectly. I have tested keeping ice cream cold and after 10 hours in the car the ice cream was still solid. I use them nearly every day to take food to work. Hot soups, teas, ice cream, salads, etc. they don't leak and because of the wide mouth, they are a breeze to clean. I have several and can't recommend them enough! Super amazing!

      The fantastic food flask.

      • Familiarity: I've used it several times

      In typical Hydroflask fashion, this food flask is awesome. Like the review below me, it's better at keeping cold items cold, but hot items still stay hot for a longer than they would if you used a Pyrex dish. The bright green is a bit more kelly green than it is lime, and super easy to spot in our myriad of red and clear tupperware.

      Great for cold

      • Familiarity: I've used it once or twice and have initial impressions

      This does a great job keeping things cold....wish it did a little better keeping soups and other hot items hot for longer. Other than that a great product.
