This will be for the PCT, starting in socal.
Clothing worn to bed in either situation:
-TiGoat Bivy
-GG Torso length 3/4" sleeping pad
-L/S Capilene 1 shirt also worn while hiking
-Capilene 1 bottoms
-Golite windshirt
-fleece beanie
-Buff around neck
-Coolibar gloves
Insulation options:
A) Arc Alpinist quilt
B) JRB Shenandoah (~45*) quilt with WM Flight jacket
I'm thinking that the amount of insulation in both systems will be about the same. I like the second setup a bit more because it gives me insulation to wear around camp. The only downside is that I worry I will lose insulation fairly quickly when putting on the jacket while my only shirt is sweaty and dirty. i suppose frequent washings may be necessary. Then again, I could always wrap the Arc Alpinist around my torso for warmth, but that's no fun when doing chores around camp…
