I did a late fall hang at valen's conservation area and overnight my feet got really cold although the overnight temps were around the 0 deg C.

I had dwon booties on and tried a few time during the night to get my feet warm but just could not. in the morning within a few mins of getting up my feet were fine again.

I had a under quilt that had some gaps. but i was thinkinh the maybe if my head end was high than that mayhave been the problem. or maybe it was the under quilt i had with the gaps. I have a new Leighlo FL 20 deg under quilt coming maybe that will help alot.

could it have been the fact that the blood came out of my feet?
