So REI has 25% of Marmot bags and I have a $140 return receipt to burn. I live in Charlotte NC and hike in WNC (summer, spring, fall, maybe winter) and I was wondering whether I should invest in a 15 degree bag or 30 degree bag. My choices are for the 15 degrees: helium or pinnacle. 30 degree: arroyo or hydrogen.
I like the idea of a less expensive, lower weight 15 degree but Im not sure how low of temps I could use it even wearing some layers.
I like the idea of a warm, light weight bag but Im not sure how much winter camping I would do so Im not sure how much use I would get out of it.
I know these are vague observations but if anyone with some experience could enlighten me and make my choice easier I would appreciate it.
