How long does food stay cold in this? (Assuming I put a couple of reusable ice packs inside)

put ice packs in mine. it is cold 9 to 10 hours later. If you preheat the thermos it will go just about 24 hours

Ice packs work great as well a frozen drink ( gatorade) thermos stays cold all day too

I keep mine in the fridge at work. It's not insulated to keep cold food cold or hot food hot for long periods.

No, not really hard, just somewhat stiff. It is not intended for keeping food in a cooler; it is intended for cold therapy. I suggest you look for a different kind of ice pack that is intended for coolers.

I use cold packs in the lunch bag with the Lunch bot and it stays very cold. My kids have loved them.

I find with cold food it needs an ice pack so I imagine you would need to use an insulated thermos to keep foods really warm/hot.

Hi. I have never tried to keep the ice pack in the cooler bag for more than 7 hrs. So im really not sure how to answer your question. I really doubt though, that the ice can last that long

I would estimate that it keeps it cold for about 3-4 hours. And no, the ice pack doesn't have to touch the food.

It will depend on the temperature of the air around it. My younger son takes one to school for lunch. They have to leave their lunches outside. His food is warm by 2:30 when he gets out. My older son takes frozen drinks for after school sports. They are still frozen at 4 when he starts practice. His PackIt stays inside all day.

No more than a couple of hours, but your freezer may vary. I keep mine kind of cold, but I store these on the freezer door, so that has a tendency to affect things on my end.

It depends how warm the environment is, how much food you'll have and how many ice packs you'll use. The more you use, the more likely the food will stay cold/frozen.

I guess you could, but once you remove the ice cubes to put your food inside, i am sure it will lose it coolness regardless within several hours. The bag is meant to be frozen by folding it up without placing any contents in it. For me any insulated lunch pack will work just as well with a ice pack. What I do is the night before I place a bottle of water in the freezer, about 3/4 of the way full as use that as my ice pack, and then when it melts I have a nice cold drink of water, the alternative is much cheaper than this bag.

I use it during school, leaving at about 7 AM and returning around 5, and the ice pack is usually still somewhat frozen when I return home. Granted, I'm not leaving it in a hot car, but I think 12 hours isn't too much of a stretch!

If you put a cold pack in it, it might stay cold, but it is just like a regular Tupperware container when it comes to keeping food warm or cold.

its insulated but it will only stay cold for about 3-4 hours. ice pack is best

I don't use it for hot food, I use a cold pack. I would say it is not insulated so I don't think it would keep hot very long at all.

Hello! I'm not 100% sure about heat as my sons school asks we not pack up items to be heated but it stays cool for about 2 hours. Longer if we place an ice pack on the exterior lunch box we purchased. Hope this is helpful!

I've never put food in the cooler just beverages. I have taken this cooler fishing and to the beach all day with drinks in it and they stayed cold all day long. I do put ice in with the drinks to keep them cold.
