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

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.

My Son’s been using us for school for a while now and I can say that it works great. He is in fifth grade and can open it by himself, but it stays tight enough that he can have pasta or things that have sauce and it does not get everywhere. It’s easy to clean even the seal comes off easily and goes back easily. He tosses it around everywhere in his lunchbox, and it has never spilled. His lunch is four hours from when his hot food goes in and he says it it’s always still warm.

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!

color is beautiful, size and wide mouth are great (18oz), but it leaks! I put hot water in it to warm the container before adding the warm food so it would maintain it's temperature til lunch time. When I tipped it over to test the seal/leakproof abilities the water came shooting out. Assumed the seal was misaligned, but I don't see anything wrong with it. Adjusted seal and tried again and same result. I usually only take dry like foods, so I'm going to keep it, but this is super disappointing. Food could have been a bit warmer, but overall the temp was alright.

The color is so vibrant! Plus my food stays warm until lunch time. Over 6 hours later

Great, perfect size, exactly what I was looking for. Does the job. I can't ask for more.

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).
