silk...more research ... no sleep for the weary .. just looked at lanolizing .. I can also lanolize the wool...it's cheap and quite easy .. now to figure out silk .. it ain't cheap .. or what type of silk would work .. I have the Sea2Summit Reactor Thermolite Liner ... umm...wonder if I should cut this up...lol

Silk is actually quite inexpensive if you shop around. The main driver for the lanolin would be the wool more than the silk.
When I was thinking of my design, I was leaning more toward using small buttons for the quilting rather than quilting with a knot. By having the buttons, I could remove the shell and treat it one way while having the same option with the the batting. That would let you launder the shell by being able to wring it to get the dirt out (which is more likely on the shell) and not be as harsh on the batting. It could also allow for having two sets of batting for one shell- one thicker and one thinner. Just unbutton the shell and swap the batting.
Hello Yes I am back ..older wise-*** and an owl covered with white hair.... and guess what - many YEARS working with wool. Realize no matter how you trap the air against your body, in a moisture condition wool will retain the water and Polypro will not - you are comparing a wool sweater from a long time ago with a undershirt from Under Armour its comparing a natural fiber with a manufactured one....
Don't take my word for it, if you spent some time in science - you can build an easy box from scrap wood to test for it... Very happy to help if wanted
There was an Old Man with a owl,
Who continued to bother and howl;
He sat on a rail, And imbibed bitter ale,
Which refreshed that Old Man and his owl.WOO
The differential in temp between the inside of the wool undercover and the outside where the fog is should allow the fog to condense on the wool and still allow the vapor inside to escape. Unfortunately the inside will probably only be able to escape as far as to the outside of the fabric. Basically you're really counting on your body heat to push the vapor thru the fabric. But if there is visible moisture out there (fog) I doubt you can maintain a level of heat differential all night, eventually the wool is going to match the dew point and the vapor will condense on it. Which may be better than on your underquilt. Fog is just a difficult animal to tame especially in an open shelter like a tarp. If it were very cold out you'd be in better shape that at a temp where fog is present. (At least that's how I'd imagine that would work, I'm not a physicist but I did sleep in a Holiday Inn Express last night )
Good luck,

Whole lot of naysayers here, hmmmmmm!!! I say go for it! You could go to Sportsman Guide ( here: http://www.sportsmansguide.com/net/s...blanket&eMode= ) to get military wool blankets at a decent price (you might be able to find some cheaper with a little google foo)!
Take your idea and make it happen, test it out and let us know the results! Just because someone else has tried it and failed does not mean that you will, as the saying goes "no one's perfect"!
An awful lot of great pieces of gear have been made by the exact thought you had, hmmmmm I wonder if this would/could work???????
If it works it would be a "Great" car camping, or base camp gear item! Then you could star looking into lighter options keeping the same idea in mind, that being "Wool" of course!

I don't think anyone suggested that it wouldn't work. I believe the consensus on using wool for a weathershield is that:
1.) Using blankets would be a quite heavy proposition. When used on top and bottom.
2.) Lighter wool fabrics probably are not durable enough in regard to the comparative tensile strengths of lighter synthetics.
3.) Wool would probably have a better application and provide more benefit closer to the hammock occupant than the distance that a weathershield would present.
