So far, I've used Hotties as body warmers in cold climes. What do other folk use? Is there something better?
And aching backs

Hot water bottles? Sometimes I'll fill two or three from my Ghillie kettle. The fuel's cheap enough.
I've used the reusable boilable things that set solid when they cool down and they're pretty good, but they're a bit of a pain to boil up and they aren't generally big enough for serious heating. It's better to use them while they're still hot from melting them, you get more heat out of them that way. I worry about them bursting after prolonged use. I've had a couple of hot water bottles do that, so I keep them in an Ortlieb bag if I've worried about a burst.
