So the wife and I are newbies to the world of backpacking (I have camped a lot in my life - but not backcountry camping. We do a lot of hiking, but always end up back at the hotel. I think I have finally convinced her to do some hike in camping. I am looking at gear, and wanted advice on sleeping back. We will be doing the NC mountains as late as October (mid 30's low). I don't want to spend an arm and a leg in case we end up not truely enjoying it.

I would like to spend <$100 and one that packs (obviously) as small as possible (within reason - I have read the issues with over compression, etc). I do not like the mummy bags as I tend to roll a lot while sleeping-I have tried them, and just don't sleep well.

Any recommendations? I saw the Ozark Trail Climatech 40F
for $40 - it sounds like 40 is pushing it - more like a 50 degree bag, it pacs supper small, but probably not warm enough for us.

thanks!!
