I took my 0F Incubator down to 12F. At the beginning I had some fresh spots near to the neck, so I started adjusting. Then I felt a little fresh at the butt.
Finally I stretched out to look for the HG label and realized that head/foot was mixed up. I just turned around in the hammock and slept well and cosy until 6am.
As advised, I tied the quilt very close and tight to the hammock.
