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/

Of course!! Put the bottle in a pan of warm water until it is as warm as you like.

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

It is in powder form inside of clear gel capsules so the likelihood of freezing or high heat should be no problem. The bottle also contains a drying agent too , but not sure if that does anything.

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.

Based on my usage of the product I would think it could be as long as the surface is clean and dry. I don't think it would be best to use the product if it was frozen. However, I think you would be well advised to contact the manufacturer. This stuff isn't cheap and if you didn't get a perfect seal, a little water leaking in over time, will cause the most damage.

For long lasting ice, save your 16oz water bottles. Fill them almost full with water and leave the cap just a little loose and put them in the freezer. When frozen securely tighten caps. Use the frozen bottles in place of ice cubes to keep an ice chest cool and they will last DAYS, and you can finish them off as ice water. I've done this for years and it' amazing how long they remain frozen.

yes. but you don't want to get the whole thing wet before you freeze it. just a corner. otherwise your baby will be soaked when it melts.

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

Yes, but if you have a water bottle with cold water in it, you probably wouldn't want to put it in there, just because it may get wet or cause a problem with humidity and temperature changes. You know how electronics can be with quick temperature changes.

Not above freezing. Regardless, if you drop it once, it will crack. For the price, your better off getting three similar bottles from Walmart.

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. My guess is no.

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

Theoretically you could, but I'd have concerns with heating up from frozen and glass cracking, just like any cooking situation. You'd be much better off freezing in bags, I use Lansinoh Breastmilk bags, put the frozen bag in the fridge the night before you plan on using it or 15 min. in warm (not hot) water, transfer to bottle and heat.

I personally would not freeze liquids in it but the Use and Care Instructions say it is freezer proof to 20C/-4F

I never tried that. That might make it work better. I really wouldn't buy the item. It realljy doesn't keep the bottle chilled well.

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.
