I'm going on a my first trip with a hammock: a 3 day car camping trip in a couple weeks where the average nighttime temp goes down to 35F. I'm not sure of the long range forecast yet.
I have a HH, a 30 degree synthetic bag (which I believe is more like 35 and which i would probably use as a quilt), an oware pad and a mummy shaped Insulmat SL-basic (R 2.9).
I do like to sleep in cooler temperatures generally, so I'd say I sleep warmer than average, but I'm not sure by how much. I don't have enough experience in the backcountry to analyze this intelligently.
Am I going to freeze my rear off? I have a second 30F synth bag that I will probably bring with me as a backup plan. I also will have a bunch of good clothes, fleece balaclava, etc.
