Sleeping bag on Aconcagua
Also called: Expedition sleeping bag, Sleeping kit (bag and mat, for the overnight)
What it is for
Keeps you warm through the night in camp. On the coldest mountains it is the single most important thing you pack: you cannot climb well after a night spent shivering.
What Aconcagua asks for
Standard
The whole climb: −30 to −20 °C comfort, you carry it
A second bag: a convenience, not a need: the carries are short; its one use is to leave a bag at Camp 1 so the next carry up does not include itoptional
What to look for
- Comfort rating (ISO 23537)
- The lowest temperature at which a typical adult sleeps comfortably, measured to ISO 23537. The limit and extreme figures on the same label are colder, and they are survival numbers, not sleeping ones.The gear lists ask for one of five comfort bands:
- 0 to 10 °C comfort (32 to 50 °F)
- −10 to 0 °C comfort (14 to 32 °F)
- −20 to −10 °C comfort (−4 to 14 °F)
