How long does the mask stay cold for?

I'm not 100% sure, but it was long enough for me to fall asleep with a migraine. 45min-1hr

About 45 minutes and it will be cold again. For it to be completely refrozen a couple of hours. Having two allows you to alternate them without having to wait. I have three.

It depends on how long the ice pack has been in the freezer before it is used. The ice pack had been in the freezer for two days when I used it the first time and after an hour it was still partially "frozen."

I used it for 30 seconds on my face, but it remains warm I belive for at least a good 3 to 5 minutes. It is not advisable to leave it much longer than that. Hope this helps.

about an hour or 2 depends on how cold the item was when you put it in there

It gets cold very quickly, 20 minutes will do but it doesn't stay cold for very long. I've found the best time window is 2 hours in the freezer. I love this ice pack!

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 have used it twice for the same purpose as you state and it was cold 24 hrs later. Keep in mind the tempature of where you are using it will determine how long it keeps cold. I used it for a plane trip across country.

Couple hours at most. It doesn't stay cold all that long, but its ability to wrap is awesome.

That depends upon how long you can blow through the mask. The mask itself does not provide oxygen.

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.

A couple hours. They don't freeze solid, but they do stay cold for a while. I feel they work better than ice due to no melting. My wife and I use them all year to keep a small cooler, cold. They are great!

I've been using this product for months; it stays cold a long time after I use it. So if I put it right back in the freezer, it I think it only takes a couple of hours to freeze up again. Honestly though, I've never timed it because I bought 2 of them (1 to take to work). So if you put it right back when you're done, the time to refreeze is short.

It stays pretty cold. If you are worried at all, I would put in one or two small ice packs just for extra chilling.

I sincerely doubt it. This product has been a huge dissappointment. I would estimate that this ice pack would stay frozen for 4-5 hours.

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.

The pillow stays cool for approximately 20-30 minutes. You shake it to redistribute the filling and keep the coldness longer. It's best to have two on hand to alternate when the filling warms up from your body heat.
