It’s a pretty common winter camping trick to fill a water bottle with boiling water, put a sock over it, and put in your sleeping bag while you sleep. Works extremely well!
- Lio 5y agoI just replied the same thing. It’s an excellent hack. Was going to add a warning not to drink the water from plastic bottles though due to plasticisers. Unlined Ti metal bottles should be fine though.
- blacksmith_tb 5y agoI'd say that argues for using the ol' Nalgene etc. only as a foot-warmer, and drinking out of the metal bottle?
- Lio 5y agoIdeally yes but it's really hard to find fully metal driking bottles. If you buy something like a Sigg aluminium bottle or no-name copy it will be lined with some kind of plastic. If you use a light weight drinking bladder that will be plastic too. I've read that risk is much higher if you apply heat to a plastic container. This is why you should avoid microwaving in plastic containers. So that leaves you either only using a cold liquids in plastic and accepting some risk or buying expensive (and relatively heavy) titanium drinking bottles.
- rkk3 5y ago> Ideally yes but it's really hard to find fully metal driking bottles. Klean Kanteen?
- Lio 5y agoJust looked them up. Looks really nice. Maybe a bit heavy for me when hiking but really nice for day to day stuff. I like the Vargo stuff. Also the new Keego flexible bottles look really interesting.
- mprovost 5y agoUsing an insulated bottle kind of defeats the purpose which is to transfer heat from the water to yourself. You'll wake up in the morning with a bottle full of hot water but you'll still be cold.
- Tcepsa 5y agoKleen Kanteen sells non-insulated metal bottles as well; I've used them for this purpose (not sleeping, but holding against my body to help stay warm in a cool room). Bonus: once the temperature drops far enough you can also drink it for a quick internal thermal boost, if needed.
- mprovost 5y agoModern Nalgenes are BPA free and don't contain plasticisers.
