Last night I tested out the Ultra 20 in the back yard. I had a recorded temp of 27* low with sleet and rain mix.
I used a ASI tarp MLD Bivy GG nightlite, thinlite and Ultra 20.
I wore a Patagonia Capalene shirt, columbia midweight fleece shirt
Patagonia Midweight capalene pants with my GSI rain pants over them.
A turtle fur Beanie and my JRB down hood.
This is very similar if not identical to my setup on most trips for this temp range.
I woke up 1 time due to discomfort, but the quilt kept me warm all night. I do stand correct from my posts above. it doesn't loft what I expected, but it gets the job done. I do think 20* is a good rating for it. but it was not a big difference from the feel and warmth of my JRB No Sniveller.
