Hydrapeak 25oz Stainless Steel Vacuum Insulated Thermos Food Jar | Thermos for Hot Food and Cold Food, Wide Mouth Leak-Proof Soup Thermos for Adults, 10 Hours Hot and 16 Hours Cold (Aqua)

I really love this thermos, especially because of its wide-mouth design. It makes it so much easier for my child to eat directly from the container at school, unlike other thermoses with narrow openings that can be frustrating for kids to use. While it doesn’t keep the food as hot as some other brands, it still does a good job. By lunchtime, the food is warm enough, and my child has no problem enjoying their meal. Overall, the ease of use and kid-friendly design make it a great choice!

I really like this thermos. Well made and keeps things hot for a few hours. Tip, put really hot water in the thermos and close lid for 5 minutes then dump out the water and put your really hot soup or spaghetti etc in. Even after a few hours, everything is still hot enough that you have to blow on it to cool it before you eat it. Lastly, don’t over tighten the lid because it will jump a thread and be loose. But snug it and you will have no issues.

Keeps food warm very well . I recommend this to anyone who travels and eats ants warm food to eat.

I got the middle of the three sizes (25 oz) and measured the thermal time constant, starting with the thermos almost full of hot 89 C water. _IF_ you don't fill completely full, AND you keep it upright so the contents do not contact the inside of the lid, then you will loose half the temperature difference in every 4hr 45min time period. So, if you start with boiling (100C = 212 F) and it sits at room temperature around 21 C = 70 F, then after 4 hr 45 minutes, you lose half the temperature difference or about 40 C, so the contents will end up at 60 C = 140 F which is considered a good serving temperature for hot soup. So if your soup was boiling at 7:15 am, it should be the right temp at noon time.The body of this flask is only 5 mm thick, but the vacuum insulation works well. By contrast, the wide lid is simply plastic with some foam inside and it does not insulate so well, so if you store this sideways or inverted you will lose heat faster. The seal is formed by a thin silicone gasket around the top rim of the lid. It sealed fine for me as new, with clean threads. If you get that surface gunked up, and/or don't carefully thread on the lid and close it tightly, then no doubt it will leak.The smaller 18 oz size will not hold heat as long, while the larger 32 oz size can do better (IF it's filled full).

Purchased this in 2 colors as my kiddos were unhappy with cold lunches. We are all very pleased so far. I pour boiling water in them for about 3 minutes to get the temperature up then put in the hot food such as rice and chicken or pasta etc. Usually I do this at 6:30am and my kids have lunch at 1:00pm and the food is still warm.

It's not bad for what it is. I'm not sure how long the rubber seal will hold up. It is pretty thin and flimsy. With repetitive opening and closings, I've already seen the rubber get caught in a weird angle and not make a complete seal. You have to watch what you're doing and make sure the lid carefully goes on or you're going to have some spillage. The outside is just like any other stainless steel container so no issues there. If leaking is your concern and you don't want to spend the extra few seconds making sure that your lid goes on properly then I would look somewhere else for a different container.

Great for the days I want a hot lunch.

This thermos is super cute and fits perfectly in my kid’s lunchbox—definitely a hit on looks and size! It keeps food hot for about 4 hours, which works fine for early lunches, but after that, it’s more warm than hot. Still, it’s great for soups or pasta and makes packing lunch so much easier. Just wish the heat lasted a bit longer!
