I am experimenting right now with different quilts for winter. I am a cold sleeper, I do sleep properly clothed for each condition and have experimented with using rain gear as a vapor barrier.
45+ JRB Shenandoah, MLD Superlite bivy
35+ JRB No Sniveller, MLD Superlite bivy
25+ Golite Feather bag, MLD Superlite bivy
15+ Golite Feather bag, JRB Shenandoah, MLD Superlite bivy
5+ Golite Feather Bag, JRB No Sniveller, MLD Superlite bivy
I have tested all but the 5+ setup. here in east TN it rarely gets that cold and the chances of me being out in that temp would be unlikely. I would love to go to quilt only. with both quilts together i get around 4" of loft which should take me to 5+, but I haven't tried it and it is heavier than the Golite alone. I have the golite at 33oz stuffed and I have the 2 quilts together with down JRB hood at 37oz. Anyone have suggestions or tips on combining quilts?
NOTE# I am trading in the feather for the Ultra 20 and shaving 10oz. it should make the setup lighter and more efficient.
