How long do they stay cold? Thanks

Not as long as I would like, but it kind of depends on if you have them just lying on top of your puffy eyes or wedged between your back and the bed which would be warmer. I actually will buy a regular larger gel pack next time because their thickness allows them to stay cold longer, but these are fine for very small areas, and you can rotate them if you're not using them all at the same time.

Yes they do n they really last 2-3 hrs. Tops wont keep ur toes warm either if its really cold they only keep ur soles warm

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

They stay warm for about an hour. If you need to have warmth for five hours, bring more than one (like maybe 5)...

I put them in late at night and have checked in the morning and they are still warm. I would say a good 12 - 14 hrs at least. Usually I have replaced them by then to make it through another night. Use them as warmers for strays in my neighborhood.

I wish I could tell you. Mine are not super tight & it's been super cold where I am & I have found them to be good. Granted--on one case I did add hand warmers but it was 4-degrees & windy.

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

About 2.5-3'. They are pretty flimsy, there's no real protection from cold. Spend an extra twenty and get better quality.

Hi Kelly, the bags will NOT keep items cold for as long as you need them to. They will work for about 2 hours. I personally am not impressed by these bags the more I use them.

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!

We have only used these for cold items. Though I have not tried hot items, I can say they keep the cold food cold for at least four hours in my children's school lunch bags. We do not use ice packs.

I wouldn't know specifics but I've put one in my insulated lunch bag and it lasts many hours. One day it was still frozen when I came home (9 hours later) . I normally don't use them for that, I use them for a shoulder sling with an ice pack slot.

I find that about 12 hrs in a deep freeze will get them cold. I work 12 hr shifts and if I have the packs frozen the day before the last approximatly 3 hrs each. I don't wear for the first 2 hrs of work and I'm cool all day long

I would say about an hour although I wouldn't ice anything for that long consecutively. It freezes pretty quickly also. We love these and use them all the time.

I suppose they sweat after a certain period of time. I put them in a small cooler of mine that I use like a lunchbox. But I use it as more than a lunchbox, really, because I like to have at least two meals with me at all times -- and they last all day -- i.e., at least 8 hours. But I suppose there are days when I don't get home for maybe 12 hours, and the stuff in my cooler is still cool. By then, the fit and fresh coolers are melted inside, but still cold. And obviously, sweating a bit. I just checked the stuff that I put in there at about 8:30 this morning -- almost 9 hours ago -- still cold. Hope this helps.

I bought mine four years ago from Amazon and am using them right now (0 degree temp outside!!!). I think they may put out a little less heat than they once did (though I'm not sure about that), but they're definitely still usable. Seven hours on, they're keeping my hands very cozy.

The gel packs are 5" X 10". There are two because there are two pockets in the shoulder wrap to cover the entire shoulder. I find that they stay cold about 30-45 minutes. I have never used them hot as they are not microwavable and it's too much of a hassle to heat water to warm them.
