Heading out from July 25-Aug 4.
Alpamayo, Huayana Pototosi, Ilamani.
I have a 0F and a 20F bag, looking to figure out if the 20F bag is enough. I have a silk/cotton liner, that is probably worth 5F which I can use with the 20F bag.
Also, should I bring a real parka or can I get by with a puffy and down jacket?
