Frozen water bottles

Discussed at length here. Good info.

Winter Water storage

I've had 2 issues with this exact problem. I filled my Nalgene and screwed the lid on and took it into my hammock. Got a bit wet.

Now I pour the boiling water in the Nalgene, screw the top, wait a couple of minutes and re-tighten the lid. No leaks.

I think my problem was the opposite of what you mentioned. I think the threads were cold but got looser when warmed and thus leaked. By waiting until the threads were warmed up and re-tighten I got a snug fit.

The issue with Nalgene is that the bottle itself is polycarbonate but the lid is polypropylene, which distorts a bit with heat.

The winter arctic canteen is reliable but heavy but is worth the weight.

I’ve used nalgene, single walled steel (Klean Kanteen) and double walled steel (hydro flask) for winter camping, they all work but have their pros and cons. I prefer the hydro flask as it keeps the liquid warmer longer but you give up some capacity with double wall. All can be reheated/thawed by putting them in water that you’ve heated.
Be careful about freezing Klean Kanteen, I had one split completely across the bottom after it froze and they recommend not letting them freeze.

You can also use a couple of plastic bubble mailers, using a rubber band around the 'package' to hold the folded ends together.

I use a Nalgene Hard bottle and put very hot water in before sleep. Put that in a Gallon baggie for redundancy. Warms you. Ready to go for breakfast from the hammock.

I have been putting mine on the ground underneath me and covering them up with a bunch of leaves. No problems with frozen water as of yet. Been down to 19 degrees. May not work at temps colder that that.
