I have a new favorite fabric for being more comfortable while skiing! And that is Smartwool! I expect any merino wool fabric will perform the same, but Smartwool has a nice product line. I have occasionally worn their socks, and have long worn their glove liners, but now have moved onto a Smartwool base layer shirt and gloves and socks full time.
The wool is claimed to be non-itchy and probably is. It is so close to non-itchy that what I find may be imagination. What it excels at is comfort when damp (much less clammy than the Sporthill synthetics I also use) and warmth. I have also tried the Smartwool long underwear and found it to be extremely comfortable, just the thing for 5 or 10 degrees F.
Wool can be expensive, but it is reported to wear like iron. Bargain purchases can be had at www.sierratradingpost.com . If you give them your email, they often send coupons for free shipping and up to 35% off anything.

I agree with your love of Smartwool! I have the base layers in all three weights, beanies and socks. My only complaint is the beanie still seems itchy where it touches my forehead although the Merino is suppose to control that itch factor you usually get with wool. I use the base layers when backpacking in the Smokies in all but the hottest months, they are pretty much my go to sleep system.
