I'm a Florida boy about to venture on the AT outside Bryson city the beginning of October. Temps can be 40-70. I have a Kelty 30/50 sleeping bag.
I'm afraid that I'll be cold at night. I will be including some long johns and a balaclava (ski mask).
I was wondering if anyone had opinions on whether a sleeping bag liner would be a good idea here. Or should I just buy a cheap down / fleece jacket and sleep in it?
