Vapor Barrier Liners (VBLs) for boots
As a fan of winter camping I have a great fondness for warm feet.
For me that means a vapor barrier to keep my sweat from wetting the insulation (socks, boot liners and boots).
I've found that the best VBL socks are thin neoprene diver's socks that I seam seal with sealent used for urethane coated tents. Be sure to seal both sides. These socks are also WARM!
1. thin poly liner socks
2. thin (1/8") neoprene divers socks
3. Gore-Tex boots or felt pac boots and (for non-camping trips) Mickey Mouse military style winter boots.
>At night I remove the VBL socks and the liner socks and put on clean liner socks and heavy wool "sleep socks". DO have a clean pair of poly liner socks for each day.
> Turn the VBL socks inside out to dry a bit in the tent then put them inside your sleping bag so they will be completely dry and warm in the morning. Put the skanky, sweaty liner socks in a Ziploc bag.
> Next I remove liners from boots such as the foam liners from telemark ski boots or the felt liners from felt pacs.
>The liners go into the foot of my sleeping bag. In the morning they are warm.
> I "telescope" my boot tops over each other to keep out snow and lay them outside the inner tent but inside the vestibule.
>If you do not have boots with removable liners then try to put them in a stuff sack and into the foot of your sleeping bag. This is why my winter sleeping bags are the long versions.
