Before I begin, I realize everyone is different when it comes to sleeping and warmth but I'm hoping to get a general idea about what degree quilt to get for an early March start for a 2019 thru. I have a 30 degree under and top quilt from Hammock Gear and used them on the Long Trail in July. Absolutely love them but I know they won't be warm enough for March. However, I'm stuck between buying a 10 degree or 20. I don't consider myself a 'warm' or 'cold' sleeper. A 20 degree is more versatile but am I flat out going to be freezing if I buy the 20's. I'm going to be wearing a wool sleeping layer, socks, and I have a nanopuff that I can layer on top as well as my buff but I'm still unsure if I'm cutting it too close and should opt for the 10. If we have another frigid March with nights that dip below 20 and into the teens, could I get away with a 20 and sleeping layers? I would rather have the 20 because I could use it for longer....For those of you in sleeping bags, do you normally use a 20 degree or 10 for March?
