Long Johns--that work?

[JD Spydo]

OK guys I know you are already thinking that maybe this is a silly topic but with winter coming on I personally think it is very important to those of us who MUST work outdoors. I just saw a video explaining that long underwear that do not wick the moisture away are actually more detrimental and hazardous than they are of any help.

The video showed the importance of having a material that will wick the moisture away from your skin. I have heard that "Merino Wool" has these properties. I was wondering and particularly you guys/gals in the armed forces ( or anyone who works in Arctic regions) if any of you know NO ( 1 )? What is the ultimate best fabric/material/polymer that is the ultimate best for thermal protection? No ( 2 ) Where is a good source/vendor to get these dry, thermally efficient long underware?

Also any input on clothing insulation would be highly appreciated as well. Thanks a million in advance

Hey JD, based on lots of conversations with folks who spend lots of time at very highaltitude I have two brands/materials that are probably considered the best for thermal insulation and wicking.
synthetic would be Patagonia's Capalene, ranges from silk weight to expeditin weight and is super stuff
Natural ie. Merino wool, icebreaker brand from New Zealand, not cheap but warm, wicking and doesn't develop the funk that synthetic will after a few days of wear. This isn't a big issue unless you are out in the wilderness and can't change or wash.

The patagonia stuff is lots easier to find and somewhat cheaper though not exactly inexpensive take a look at the patagonia website, REI, or any other outdoor site you like.
