Do these bags keep fluids warm in the winter?

They will suffice for keeping your beverage warm for a short period of time, however the purpose is more to facilitate carrying a water bottle rather than keep it warm or cold indefinately. It would be best to consider a fully insulated thermos or travel bottle to keep your beverate warm longer.

I think so, because of their insulation filling. But I've only used them to keep my Royal Caribbean unlimited soda package glasses cold in the heat -- and for that, it works great.

I have never used them to keep something warm. I only use them to carry my water bottle around. Sorry!

It helps a little. But I use one of those cool coffee thermose mugs like (amigo) and holds it just right!!! I hold a thermos large one for my coffee and it's great!!! But the "amigo" mugs work real good :-) for the price, it's a great bottle holder. (Hot or cold) what ever size. The amigo mugs you can get great deal at Costco right now :-) happy holidays

I really don't like them at all. To big for water bottle and it didn't keep them cool, so it probably not keep anything warm either. Very disapointed in the product.

I have only used mine for cold drinks and they do a decent job of that in summer weather. I would have to guess they would work equally well with bottles of warm liquids for a period of time also. They aren't double walled like some containers you can buy else where and generally do keep hot/warm liquids warmer for a longer period of time.

I've never used the bag for hot items so I can't say. I only use mine for my cold water bottle, and it works great for that.

They hold the same volume as a regular grocery bag, only turned onto it's side so it's more stable and does not crush the items on the bottom of the bag. The cool bag keeps frozen items cold even in summer heat.

I don't know. I use them in my closet as sorters. Hopefully, my closet will never get that cold!

Yes they do. Don't leave them in hot environment or they melt. They work really well.

Not really; there isn't much for insulation. But they have a very functional straw and closing system.

Yes. You need to know that this bag is quite insufficient for warmth in temps below 60

Hi. This bag may have the same type of insulation since it works very well. The zipper bag inside helps to mantain the cold. Everything is close tight. The gel ice that comes with it (Cold Pax) it's great because it maintais cold better than other brands I have tried. What I have found to be very useful (specially in long trips) is to use two gel ice packages (one in each of the inside bags) instead of one. The advantages of this product over a cooler is that it is much easier to handle than a cooler

My kids use them with out hats or bennies. They haven't complained about the cold yet. I got the XL for them and tightened it down. Works great.

Only one person on here is right, these packs stay cold forever without refreezing them. Anyone who keeps them in the freezer is just wasting energy. They use nano-size perpetual motion devices as minature a/c units and vent through osmosis.

They will help, but are maybe not thick enough for serious thermal protection. Excellent, though, for keeping road-salt and ice from paws. 3rd winter, 2nd pair.

Sometimes it does, sometimes it doesn't. I try to keep them upright. They do keep drinks really cold! Things will still be nice and cold the next day.

It depends on what kind of cool packs you use. Their really is not any insulation behind the linner so you will need some type of cool pack to keep it cold. Otherwise without cool packs the answer is yes.

Yes. The ice bag does not "sweat" or leak. It keeps stuff cold for about 3-5 hours.

Yes this bag id good for winter weather, my son is 11 and he used it for camping and the weather was 18 degrees and very wind the one night and he said he was warm.

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.

yes they do. the bags do not stay air tight for long period of time. air eventually gets back in.

Sorry, I had to check with my husband, who takes these mugs with him on the road. He said, Yes, they do a good job of keeping liquids how/cold.
