If you can get the nest down to 20 and be fine you might take the coldest sleeper honor away from neo. Anything below mid 30's and I have to add other insulation.
I am playing with the idea of using a ccp from walmart cut down to torso size. I use a cc sit pad I can add. I could add my pack or gear under my legs if needed. I am waiting for some really cold weather in Cincy to test this out.
Is that too much to ask? Girls with frikkin' lasers on their heads?
