REALLY what sleeping bag rating is required for Aconcagua?

by adrock82 » Sun Jan 23, 2022 7:36 am

I've seen so many gear lists for Aconcagua with wildly differing opinions on sleeping bags for Aconcagua and it's hard trying to decipher the real info from the 'overkill' recommendations.

Currently my warmest bag is a Sea To Summit Latitude 3 which has a comfort of -10 and a Limit of -17. Basically I'm trying to work out if I'm going to be able to take that and save buying something new (since there is so much other stuff to buy!).
In saying that, if that bag is nowhere near enough, of course I will get one that is going to allow me comfy sleep on the mountain.
Out of interest, I'm pairing it with a S2S Ether light extreme pad which has an r-value of over 6 (plus a closed cell which takes that to 8 ), and do have liners for the sleeping bag. I'm anticipating though that it's not so much the ground temp up there thats cold, but the air temp at night.
