Patagonia's Capilene rocks, but it also melts... from experience it melts (and melts TO you). It is my favorite cold weather base layer, it works as advertised, is light weight, drys really fast, and as long as you aren't wearing it under a hardshell, it is stink resistant.




As far as the drifire stuff, it is significantly more durable than silk and lighter then wool making it a better choice for winter. I don't know how stink resistant it is, as I have only ever worn it with my wildland PPE which normal sticks after a day on a fire.

I like the Merino Wool stuff, especially Smartwool stuff. It may be the best natural material for being stink resistant, but it is far for good. One run in my Smartwool gloves and beanie hat and it needs to be rinsed at a minimum. They are still more comfortable and usable in a wider range of low temperatures then most of my synthetic stuff.
