Is it safe to freeze the bottle with water in it?

yes, it's made of the copolyester...it will sweat though w/o a sleeve or insulation. Link below will show you temp ranges for copolyester. http://nalgene.com/materials/

I would not recommend freezing this bottle, freezing the liquid causes the bottle to expand and then contract would cause damage.

I never used it cold, but from what I remember you just need to put it in the fridge or freezer when it's in a liquid state.

I bought a little thermometer and put it in the fridge. It will freeze soda and bottled water if set to the coldest.

Yes. It's best to wait until the milk in chilled first in the fridge then freeze it. Make sure you freeze the bottle in the back of the freezer. It should be good for 6 months.

Yes, however, you should keep the ice contained as to not damage the fan. I like to freeze water bottles.

Yes, you have to twist it to take it out and put it in the freezer. It's a little tough to twist back in once it's frozen, but totally worth it.I love this bottle.

currently my answer is NO. if the cap is better closed . l place it in my baby bag while family outing. you know that the bottle would not stand still. but there is no water in the bag.

Probably. Don't fill more than 13/16ths full. I used to fill H2O Drink bottles about 2/3 and lay them almost flat just enough where the top could be opened and topped up so a chunk of ice kept it cool. You know water expands about 10% just before freezing. Don't try to freeze carbonated drinks. It kills the fizz. Try this, put chunk or ice cubes in a dry bottle and keep it ready in the freezer for an outing. Ever froze a watermelon?

I have never tried to freeze it but it workes real good just putting cold water on it. I don't think it would be healthy to freeze it and put it on your head

Not a bag of ice but a freezer pack is OK.(you know, the hard shelled kind that have gel in them.)I freeze bottles of water and they cool it down quicker in the beginning. NEVER EVER let ice melt in it. It will ruin the motor.

I've never tried putting them in the freezer, so unfortunately, I can't answer your question. I've read over the bottle insert and it mentions nothing about freezing, so I don't think I'd attempt it.

These bottles have a plastic stopper. I would not use these to freeze in...I think they break.

I have not personally tried to freeze anything yet, but they are glass so I don't see why you could not use like a regular mason jar (leave enough space for expansion). Even if you do not use as intended, you won't be disappointed with these little jars. My friend uses the set I gave her for salad dressings because they do not spill the liquid.

My guess is no. First off, you would probably damage the bottle, and second, the bottle is so well insulated that it would probably take a long time to get the snow/ice melted. I have heard of people in AZ and other warm states talk about how iced tea, or ice water will stay for hours in their Hydro Flask in a car well over 120 degrees (they even said the bottle was too hot on the outside, but still had ice inside). Now, is it possible? I think it could be, so if you are only concerned about using it emergencies, I think you are okay. Otherwise, I would purchase a small tin cup or something to add to my pack in case of emergencies.

I doubt it. You can put anything in the bottle but It would need to be water soluble.
