I'm shopping for a 30 to 35 degree sleeping bag with a weight of around 2 pounds. My local store has these to choose from all having bags within the above limits: The North Face, Kelty, and Marmot, some with down and some with synthetic fill. If these bags all fall within my desired range and price being comparable, which would you choose, down or synthetic fill? I'd appreciate any advice or opinion or other options. On my recent section hike in the Smokies, I used a 55 degree fleece bag. The lowest temperature I saw was 51 degrees and I was a little uncomfortable during the night. My fleece bag doesn't have a hood and I didn't have a toboggan so that may have been the problem. After putting on my windbreaker / rain jacket with hood I was ok.
Thanks for your help.
