What's the best sleeping bag for the John Muir Trail?
I will be thru-hiking the John Muir Trail this summer and would like your opinion on sleeping bag. I currently own a synthetic, zero-degree bag that is an unappreciated 4 plus pounds. I know this is too heavy (as I thru-hiked the Colorado Trail with it). My real question: can I get away with a 30-degree down bag, or should I look more at a 15- to 20-degree bag? I tend to be a somewhat cold sleeper. I am 6'2", 190 pounds. I know the temperature ratings are guestimates at best, but your input would help. DaveDolores, CO
