The 2 man Bivy Sack?





The Things They Carried: The Bivy

Climber Freddie Wilkinson reflects on how ideas advance gear, and gear changes adventure
By:

"The man who climbs only in good weather, starting from huts and never bivouacking, appreciates the splendor of the mountains but not their mystery...." —Gaston Rebuffat, 1953

"The first time I held a grown man was on the South Face of Cerro Poincenot, in Argentine Patagonia."
Freddie Wilkinson

What russian ski tourers do in Siberia/Putorana/Kol'skiy/whatever when it's cold night?

They usually have a giant bag for, say, 5 people. Then everyone crawl in there with 1-person bag (built for warmer temps). The one who crawls in last also arranges water barrier so no condensation will impede giant bag.

So basically it addresses three things:
a) weight - AFAIK one giant bag + a couple of lighter-weight bags will be lighter than many full-blown winter bags; also see c)

b) everyone in group are sharing some warmth in common giant bag

and c) the dew point is moved between two bags and is not inside their insulation anymore. Combine that with DWR treated inner bags and you'll see... (and if by morning their bags have less water inside, they will be lighter)
