I have been car camping for years but am looking at backpacking now with the Boy Scouts. I am considering a Big Agnes Gunn Creek bag. I camp mostly in the Southeast US moisture is pretty much a given which is why I am choosing synthetic. Some times it gets down to freezing but not much colder. I like the idea of the sleeve for the pad and the insulation only on top. Will the insulated pad actually keep me warm when the temperature drops? Has anyone else had any experiences with these sleeping bags good or bad? I tried the search but didn't come up with anything.
