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 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.

Don't freeze your bottle! I put in 14Oz of water and mine exploded.Don't freeze your bottle. It will break.

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

I've never tried to freeze them, but they are dishwasher safe so I would assume that means they are able to be frozen. They don't expand like a throw away bottle would so you would just have to be careful to leave room for the liquid to expand.

Absolutely, I have filled mine about have way and frozen it then filled up with water, cool water for a while.

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

No, it is not freezer safe. Just the ice pack. The nice pack keeps the water cold for a good 8 hrs... Have not tried longer.

I do not use bottle warmers. But I have puts frozen pouchs in boiling water and it holds up just fine.I'd imagine you'd be fine.

No, we haven't tried freezing in the bottle, I have the long ice cubes so we just drop ice cubes down the mouth. - However if you leave room for the water to expand and don't use the lid with the bamboo insert, the bottle should be fine. Stainless steel freezes fast and nothing will leach from the metal - just make sure to leave enough room for the liquid to expand, otherwise it will expand and push right through and crack the bottle.

Definitely leak proof. Would be nervous to freeze it though. It's basically a glass bottle that fits into a protective plastic sleeve. I'd be afraid freezing it might just shatter the glass.

I admit don't know anything about algae, but I do know that these bottles have a very nice soft flexible plastic construction so I wouldn't see why they wouldn't freeze well. The tops are even nice to work with, when folded down they close nicely, but if frozen they may freeze closed therefore may need to thaw just a bit to use the flip-up dispenser to keep from cracking or breaking 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. 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.

Yes. The liquid mixes with the water on the way out. The bottle does not fill with water. I unscrew mine and keep them in a cool place. I live in Arizona were outside shed can get to 125 degrees.

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.

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.
