I'm doing a NB thru hike, starting in the middle of May (have to graduate from college first). I'm 150lbs, roughly 5% body fat and a fairly cold sleeper.
From what I've read and when I'm starting it sounds like I would need a 25-30 degree bag with a liner. Is that correct? Should I get a warmer bag and switch it out later or get a 40 degree bag, liner, and dress warm when I sleep? Thoughts?
