The setup is a MYOG double layer hammock.
A full length CCF pad inside.
2 - 1/2 lengths 3/8 CCF sideways.
Extended campmor poncho/tarp as a garlington under shell, no top.
2 garbage bags filled with crumpled emer blankets.
Ultra 20 quilt.
Heavy Johns
Thick Socks
Down bomber style hat.
This was a test run last night, 22dF when I went to sleep, 14dF this morning.
I had a 10x12 foot tarp pretty much closed up like in storm mode. Slight opening in the ends and there was some air circulation inside.
I expected some condensation. Condensation on the tarp was very very light and only at the very top.
Condensation in my quilt was heavy and it delofted about 1". I understand the conceptof condensation inside the sleping bag theory in cold weather, IE it forms on the warm side inside the bag.
Went to sleep at about 10:30 PM. I was very warm until about 5am. Very cozy and I expect that the delofting lessened the warmth a little. I was still comfortable, just a few cold spots and slept until 8 am.
Its a good setup but I need to make some adjustments like open up the sides to put the CCF pads between the layers.
I tend to sleep on my side and skrunch up and pull the quilt over my head and make a breathng hole so I know some exhaled breath makes it into the inside of the quilt.
One answer is a vapor barrier liner bag or clothes and I do have a med emer bivy (the heavy one) that I carry just in case (7oz) that I can use inside my quilt but I just dont like the clammy feeling.
Another option would be a breathable quilt bottom insulation and I think that would help, but I intend to carry CCF pads anyway in case I end up on the ground.
Third option would be to buy or build a 15-20dF climasheild quilt and just not worry about it which I may do anyway.
Any sugestions welcomed.
