I have switched from a 15 degree down sleeping bag to a MYOG climashield quilt this summer, which has decreased my base weight by almost 1.5 lbs. I would rate my quilt at about 45 degrees with no clothes. On my last trip in the mountains I had to wear my puffy top under the quilt on a ~35 degree night, which is exactly as I had planned to use this quilt.
Unfortunately I historically have used my puffy as a pillow, and I had a hard time sleeping without something under my head. My rain jacket was not a particularly good substitute. So while I was warm, I was not comfortable.
I know that a lot of people don't carry any more clothes than they need and often wear their clothes to sleep in. What do you guys use as a pillow when you are wearing all your fluffy layers?
