Curious - how do you lanolize a wool blanket?
I have some pure lanolin and as a paste it is very thick and very, very sticky. I know lanolin can be obtained in the form of oil, but at the price I have seen on-line, it seems that would be expensive.
So, how would you lanolize a wool blanket?
From the research I have done, you add a small amount of 100% lanolin (mere drops, I've read) to hot water, along with a detergent suitable for wool. Mix it up and slosh it around, then drain, rinse, and lay the wool out to dry (no dryer unless you WANT shrinkage).

I think the paste would work, but 100% pure lanolin oil didn't look all that expensive to me. A four oz. bottle is only $14.50 at this URL:
it seems to me that when you introduce fog or dew silnylon or some other impervious barrier has a place in the outer layer. Some places you need the cover to breath but others you gain more moisture from the outside than you make inside. I'd be tempted to use a bathtub underneath over the end caps and breathable over the top. In use I'd vent over the face area as most of the lost moisture is in the breath. OTOH it's also a lot of heat. If you can capture that under the tarp it sets up another microclimate that might help with the fog on top. Of course if you stay below freezing then fog and dew are not a problem. Lot's to theorize about. ;-)
Yes, lots to theorize about. Some have poo-poo'd my wool undercover/overcover idea, but I like your thinking that breathable on top is more important than breathable on bottom (though the undercover should breathe too). There are all sorts of approaches to this, which makes it fun!

Lanolized wool is not a vapor barrier. It is water resistant but vapor permeable. That would block rain and mist, but the vapor of fog would still pass through. The lanolized fiber will not absorb moisture, but the gaps between the fiber will resulting in a pretty big weight gain. Since the condense moisture is not actually in the fiber, it "should" be able to have the moisture removed by shaking it out.
