I carried/carry a small fleece stuff sack for my fuel canister that I usually use for the Nalgene bottle. It doesn't completely cover the bottle, but the drawstring holds well enough for the job. No bag back-up for leaks, but that's not a bad idea.
Word of caution; depending on which study you believe, the 'boiling' water may leach out little nasties from the Nalgene. Best bet is probably to dump the water in the morning and not drink it, no need to carry an 'extra'.
I fill it about 2/3s of the way full.
Sounds like another plus for the Bushbuddy stove, no fuel concerns. In addition you start with a least one quart of non-frozen, potable water.
A bushbuddy type stove may not be a bad idea for this, I can make one that is very lightweight and easy to carry. I like that idea. I filled mine all the way up, and since my bottle has never leaked on me, I didn't put it in a plastic bag. I also was wearing my polar fleece pants and smart wool socks, so the bottle never came in contact with my flesh. If contact to your flesh was a possability I would cover it some how.

It is worth remembering that hot water at home is recommended set no higher than about 120 F to prevent scalding. If the water starts out at boiling (212 F) it would certainly be prudent to prevent direct contact with the skin.
And be sure you're using a bottle that you can trust. Nalgene is well made.
I have tested & used Gatoraid bottles. They will deform a little from boiling water, but have not leaked for me. Might be better for those to use water that has not yet reached the boiling point or add a little cold water to the bottle.
In the past, I always put my hot water bottle in a sock or fleece cozy, then into a dry bag, but I never saw any sign of leakage, so now I just use a bottle type I believe to be trust worthy, in a sock or other cozy, but no dry bag.
I guess when it's cold enough to need a hot water bottle, putting it in a dry bag is not a bad precaustion, in case there would be any leakage.
Any bottle you're not sure about, I would test at home first before taking it to bed out on the trail.
I wonder if this could be done with a Platypus bottle. They are much lighter and would probably be more comfortable to sleep with. Anybody ever tried?
I would not try that myself.Quote:

I am sure this method would work with almost anything that can hold hot water, and then transfer the heat on to you. All I know is that it works great.

I did an overnighter (low 32d) with the scouts this past weekend. I used a 16 oz bottle in a couple of medium weight socks. Had my new BA Yampa and Exped 7 short also. I put the bottle in the bag about 30 min prior to going to sleep. It was warm and toasty getting in, in fact it was too warm. By 2am the bottle had lost enough heat that I had to incorporate my old army wool liner.
So, I need to regulate the output better to enable for a longer "burn". I think next time I'll use my 2 liter Platypus and mayble make a reflectix and/or fleece cozie for it.
