Hey all,
I'm planning a trip in late september to early october from Bishop Pass North on the JMT.
Just wondering what night-time temperatures I need to be prepared for.
I would really like to get away with taking my 21 oz 35+ bag instead of my 2 lb. 11 oz. 15+ Bag. (Layering with thick long underwear, baclava, etc., of course).
Is that going to cut it?
