Re: Vapor Barriers

Yes I have adressed the issue of circulation and in fact I hardly tie my boots at all, just enough to close in the heat. I also do not have a problem with cold extremities any other time. The problem is that even after sitting for hours my socks are almost always damp and therfore cold. I have done a few tests with plastic bags and my wool socks and I have to say that VBL'S seem to work well for me. As far as applications to backpacking what temp range do VBL'S work best, in sleeping bag liners or socks? In my at home tests the clamminess doesn't seem to be an issue because the moisture inside the VBL is always warm. Which I guess goes along with the way they are supposed to work.
