How long does this gel pack stay cold if, say, it has been in the freezer for at least 24 hours?

It stays cold to cool a couple of hours. Not sure why you need it so long, since therapists recommend icing down for only 15-20 minutes. And you always have the other gel pack you can pull out when you want a colder one.

Hi! This gel pack stays cold for quite a while, and even once the very cold feeling of it fades, it is still cold enough to keep help an aching or injured knee.

Normally I do not have them on longer than 20 min, But they are still pretty cold I would say at 30 min.

The packs stay cold for an hour or so; you may need to replace; however it's not medically advisable to leave a cold pack next to skin for over 20 minutes. I do, but I wrap it in a kitchen towel to avoid frostbite.

I love this bag. The re-useable ice pack keeps your food cold for 4 to 5 hrs. It's not refrigerator cold, but it is better then any other lunch bag I have owned. I hope this helps

I froze mine. It has special extra long lasting cubes in the gel and will stay ultra cold for an hour. You will freeze before it thaws.

I think it depends on how much water you started with. Mine will keep ice cubes for about 24 hours as long as I started with mostly ice.

It depends on your freezer, of course. I usually let it freeze at least overnight or for a long workday.

No. You need to put it in a freezer for a few hours so that the gel that sits inside each side of the lunch bag freezes solid.

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.

I keep them in my freezer. They usually stay cold for two days in a cooler. I also using them when I need to put ice on my knee or on my back.

They last probably 30 min or so, not warm yet but maybe not cold enough to be effective. I try and use them for 20 min before throwing them back in the freezer.

I have only used it for cold items. With an ice pack it stays cold for about 6 hours.

Longer than you should keep it on your body. By mistake, I've kept it on me for 45 minutes and it's still chilling. I'd say about an hour - if it's enclosed in an ice pack wrap.

It depends on how cold your items are. (Semi-frozen,etc). It will hold the temperature for awhile, depending on where u keep it. (Freezer, fridge, or on your desk). I keep mine in the freezer at work and will remove it about 2 hrs before I leave. My juice stays cold till I get home.

I use this in my daughter's lunch box and nothing in there needs to stay really cold. She eats only a few hours after it is packed. I can tell you that it is not still cold when she gets home about eight hours later. If these were used with the lunch bags that go in the freezer (which don't even require a cold pack) I have no doubt that everything inside would remain cold all day!

In the ad it says the clay pack part measures 6'' x 12'' and includes a reusable protective cloth sleeve with a footlong 1 1/2 wide elastic strap with velcro for a secure fit. It gets very cold in the freezer but I wouldn't call it "frozen." It's a oil clay mixture that stays pliable. I'd say somewhere between a half hour and an hour. I have another clay pack and a gel pack that fits in the cloth sleeve, so I can interchange them and always have a cold pack ready. I'd say it weighs about 1 1/2 lbs.

Depends on how long you leave it in the freezer. I normally can get two uses out of it before it has to be refrigerated again. It's really a great ice pack.

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
