    This link also discusses using canvas as an outer layer and backs up many of the comments made in MacEntyre's excellent post.

    I appreciate the repeated clarifications that this layering strategy has a very specific application: deep cold, low humidity, hot tent and/or a camp fire.

    Excellent write up. Forced the old brain housing group to reread it and do some work (thinking about what you said). Makes sense and good info to know and use in the cold.

    Upon further reflection, it occurs to me that the fundamental difference in that approach is that you collect all of the moisture and then dry it out.

    How do you dry everything?

    I've read that! Great information. Having the 'engineer defect' it was necessary for me to reflect on the numbers to really appreciate the magnitude of the problem.

    Us'ns in our clothing are near tropical, and right outside our clothing it's a frigid desert!

    Well worth repeating... it only works under extreme conditions.

    Thank you!

    Actually, you are likely to have a good understanding of the fundamental issue... don't you use greenhouses in winter?

    Informative post! Makes me wonder if my choice of a 1pc "Carhart" style overalls that I wore at my first winter camping trip wasn't a stroke of unintentional mad genius (of course, I've "upgraded" to Gore-tex and nylon outer layers, d'-oh!) Is "cotton duck" the same thing as "cotton canvas"?

    All that said and acknowledged, on "the night of -36" I wouldn't have sold my Sorel 1964s for $500 (rubber bottom section, leather upper), nor my MollyMac IX hammock sock for $1000

    Funny . . . I have a 50 yr old tarp that is, as good as, the day it was 5yrs old,

    weighs a tonne (That would be a ton equivilant, that = ???)

    I have had it for 25yrs, and it is toooo heavy to use for any thing . . .
    Took it car camping to use as a ground sheet . . .
    but decided to leave it in the car . . . tooo heavy.

    I have been wondering what to do with it . . .

    Bing . . . mucklucks, yea . . . I think I'll cut them up for Mucklucks.
    For the whole family

    Thanks guys

    Good to see this discussion. I've always had better luck, overall, with natural fibers than with synthetics. I tried the vapor barrier system years ago and I had to give it up. I never woke up warm and damp. I always woke up cold and wet. I don't perspire when active, I sweat like a tropical rain storm. Still wear cotton socks down to about 40* so I can get the sweat out of my boots. ( My feet even get sweaty in crocs )

    I think this helps explain my first hammocking experience. I used an old army half shelter which I believe was made from canvas which I strung between two trees and used as a hammock. It was winter in Utah and one of the coldest mornings I ever remember waking up to. The only insulation I had was the sleeping bag in the hammock and I stayed warm all night. Now that I know a lot more about hammocks I've always wondered how I was able to stay warm that night with no pad and no uq.

    Yes. Ideally, you want 300 to 400 thread count, which is lighter than 7 oz canvas.

    The ~7 oz canvas you get from fabric stores is not very high quality. Every edge has to be roll hemmed, or it will fray until it falls apart.
