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 wouldn't recommend freezing them. They are great bottles but freezing plastic is not a good idea.

Yes leave it in the freezer when you are not using. When the liquid inside the pack becomes solid, then pack it in the box.

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

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 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 think so. We "cheat" a little bit. We froze our water bottles about 25% full the night before. The next morning, we filled them with cold water, placed them in the cooler, and placed our snacks around the bottles. We didn't unpack the cooler until the next day and everything was still cold. We really like it.

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.

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.

Filling the bottle with ice and liquid can do no harm, except it may sweat from condensation. I don't recommend hot liquids.

Not at all! Even when there is ice cold water inside the bottles outside temperature remains neutral with no condensation!

Water will expand when frozen and this is a very rigid plastic, meaning I don't believe it is meant to be placed in the freezer without cracking the bottle. So it is my belief it is not a good idea to freeze the bottle without damaging it's integrity. The gel stick is re-usable, it can be frozen over and over again but the cooling effects only last for about an hour if not in direct sunlight with your liquid of choice.

It is in a glass bottle and freezing is possible but it is very well packaged so I don't think it will. The flavor though is outstanding.

Many people keep their bottles in the refrigerator (marked very clearly DO NOT DRINK). As I buy mine in gallon form, I keep them in a dark cool place in my basement (on a concrete floor). The temperature rage that has been given by many different sources average out to this: -15*F to 60*F to 65*F. Yes it can be frozen without breaking down. Be careful not to allow it to become too warm as 1) the container will swell and 2) the H2O2 will start breaking down quicker.

I have never tried that. What I do is leave a bag/s of frozen milk overnight in the fridge to slowly thaw. I then empty in bottle the next day and then warm it as I need. If I need the frozen bag ASAP, I gently thaw under warm running water. Empty into bottle and warm in the warmer.

I have filled mine with a mixture of water, salt, and rubbing alcohol. This way the water can't freeze all of the way and the ice is flexible. After use, I just put it back in the freezer for the next use. The freezing process doesn't seem to hurt the liner of the bag, because it has not leaked at all.

yes. If you hear swishing around in there, it's not cold enough. Leave it in the freezer for at least 24 hrs. It takes a while.
