Hi Hacksaw,

Thanks for the detailed information on vapour barriers.

I do not have the sweating problems you have but do find that my boot liners are soaked at the end of each day. I will give the vapour barrier between the socks and liners idea a try this winter to see how it works for me.

I remember Michel Blomgen used plastic bags in his Sorel Caribou Boots in this way in one of his Swedish video's (may have been #4, "Cold of the Night").

As kids we used plastic bags in this way to keep our feet dry when our boots were not waterproof and we were going ice fishing in the slush.

I do not know if I could get used to being clammy when I am trying to sleep, I will have to try it out. I do usually sleep in some kind of clothing in my sleeping bag as I have found that it helps with that cold draft feeling.

The Canadian military cold weather sleeping bag system has a cotton liner in the bag next to your bare skin, could this be to absorb the sweat produced and prevent it from saturating the down insulation? I thought it was just to keep the bag clean but there may be another purpose. I always thought cotton was an odd material for this use but perhaps there is a logical reason.
