Do they sweat? How long do they stay cold?

Yes, they definitely sweat. I would say they maybe stay frozen for 2-3 hours. When my daughter brings it home at the end of the day, it is barely cold.

I've never had them sweat. I pack my daughters lunch at 6:30am, she comes home at 12:30 and I unpack her still cold lunch box at 1:30

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.

Abby I did not notice a lot of moisture in the bottom of my lunch bag. I go in to work at6:30 am, have lunch at 12.15 pm: my yogart is still cold.

Whether they sweat or not is totally dependent on the humidity in the air around you. If you live in Las Vegas, as I do, you will very likely never see them sweat; in Houston, they are going to condense the moisture in the air around them!

Yes, they sweat a lot. Depending on what you place it in, it stays cold in a cooler from 4-6 hrs on a hot summer day.

They stay colder longer because of the silver backing. They are equally as durable.

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.

That's hard to answer... I live in AZ where it doesn't get that cold usually. I did wear them in the pouring rain in the low 40's...and they were warm enough for me. I would probably wear them in 30 degrees if I was dry.

NO., but I have never seen them sweat. It does stain and I cannot get it clear again. I even used bleach and soaked it overnight. It looks pretty bad when it is empty.

They would probably become cold due to the amount of sweat that would build up. They wick enough for an active job / hiking, but think it may not be adequate for a sport.

They will still be cold if it is closed and in a decent temperature (in the car or bus), but they would not be frozen. It guarantees frozen things up to 3 hours.

I bought these for my husband and he says they don't get cold or stay cold long enough.

Yes, for me in about 35+ degrees their breathable, but not well insulated so the hands get pretty cold still.

The layer inside is a little bit thick and that keep you warm! But be careful: if you are doing exercises outdoor in low temperature and you are sweaty, And you let your body cold because you done, you will feel freeze! So You have To be active everytime! And when The exercise is done put some jacket on ! Well! That is The way i use it!

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.

No they do not seem to be insulated but they do sweat with Ice. Without Ice they remain unwetted outside the glass. So they are temperature dependent I would say.

It does sweat a little if there is really cold liquid inside...not as badly as others but not totally dry.

Coldest I've experienced with them are -7°F, but they were just fine at that temperature.

No, they haven't made my feet sweat but I wear socks with them and it has been cold. They have a cloth lining in them and a great supportive foot bed that is also cloth lined. I have used them in the snow and my feet do not get cold either. They are not insulated but I was just fine and dry in them with my light wool socks on.

I haven't experienced that yet. But I only bought them to go under ski wear because I have bad circulation when exposed to winter for a long time.

indefinitely I believe. It doesn't take long to get them cold and they seem to stay cold/cool for at least an hour. I purchased two, so one is always ready.
