I'm looking forward to trying this VB sandwich setup for three nights, predicted to be about 38 degF, this weekend:

Heresy Explorer hammock
Space Blanket
KAQ quilt

I have not decided whether to use the SS OCF pad. I might want it as a holder for the SB.
Did you shape your SB any? I was thinking about using the pad as a pattern and making the SB 4 - 5 inches larger all around.
