The setup is a MYOG double layer hammock.
A full length CCF pad.
2 - 1/2 lengths sideways.
Extended campmor poncho/tarp as a garlington under shell, no top.
2 garbage bags filled with emer blankets.
Ultra 20 quilt.
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 onlyatthe very top.
Condensation in my quilt was heavy and it delofted about 1". I understand the condensation side slepin bag theory, IE it forms on the warm side inside the bag.
Went to sleep at about 10:30. 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.
I tend to sleep on my side and skrunch up and pull the quilt over my head and makea breathng hole so I know some exhaled breath makes it into the inside of the quilt.
One answer is a vapor barrier liner ba 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, 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
Any sugestions welcomed.
