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

⭐⭐⭐⭐⭐ Perfect for my son’s lunch I bought this to pack hot lunch for my son, and it has been an excellent purchase. I put the food very hot in at 7:30 a.m., and by 12:00 p.m. it’s still hot when he’s ready to eat at school. The 25oz size is perfect for a full portion, and the quality feels sturdy and well made. The lid closes securely, and I haven’t had any issues with leaks. It has made our daily routine much easier, and I feel at peace knowing his food stays warm for hours. I definitely recommend it for parents who want to send hot meals to school, has perfect size for him

Sturdy, insulated container that will keep your food HOT for several hours! I washed mine on top shelf of dishwasher with no problems. Its large enough for a good size meal but not too big to put in a lunch pail! Easy screw on and off lid. Great price!

I use this for overnight oats all the time. It’s of really good quality and lightweight. The lead comes off and on very easily. The size is perfect because you can put all sorts of things in it, like soups, overnight oats, or cereal. The portion size is also perfect. It’s also super durable. I’ve dropped it several times out of my truck, and it doesn’t even have a dent on it. I’ve also washed it through the dishwasher numerous times, and it never had an issue, so it’s definitely dishwasher safe! I’ve given several of these as gifts, and they’re a great product.

I think this is just the right size for my daughter to take lunch. She is 11. This does seem to keep the food warm long enough for her to get it to lunch time, but it’s isn’t HOT. so I think it could be a little better on that. The metal doesn’t seem thick, and maybe that’s why? I do love that it has a little handle on it. It seems like it will be fairly durable and be able to make it through some drops. It may be a little better if it had some cute designs but my daughter was happy it was pink. It is plenty easy for her to take the lid off and put back on.

Keeps food hot or cold for a very long time, and it is sleek and beautiful

This is good size for any school going kid. You can also take this on your road trip. If you store boiling water for atleast 10 mins and then dump the water and add your soup or pasta or rice, it would stay warm for 4 hrs.

The 32 oz. size is 32 oz. if filled to the brim. If you put the lid on (as one does), it is only 28 oz. If the lid is screwed on tight, it does not leak. The size and shape is good for eating noodle soup using Chinese style (25 cm) chopsticks and a long spoon. The rim is smooth and comfortable for drinking from. I have not tested the thermal retention over time yet, but pouring boiling water into the jar does not immediately raise the temperature of the outside of the jar so the vacuum must be holding. The textured surface of the exterior gives me a secure feeling grip with one hand, though note that I have large hands.

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).
