The only things I've ever tried are on my feet - I've used vbl socks made of silnylon to deal with my feet sweating and wetting out boot liners in very cold weather. Those have been very effective and I can stand them. I think I bought mine at campers village, and they don't have a brand on them that I can remember. I also sewed a pair from scrap.

I've also tried a (borrowed) VBL bag liner - and I simply can't deal with it <img src="/forums/images/graemlins/smile.gif" alt="" />

Judging by how effective they are on my sweaty feet in my kamik boots, I think the technique would probably work fine as long as you can stand stewing in your own juices.
