Base layers for cold rides?

3. Both posts 1 & 2 above are great advice.

I lived @ 7000ft for many years and I skied a lot. Best to wear layers you can peel. Windproof is essential, avoid cotton for base as it retains moisture so the technical base layers are best. Find what you like, most are pretty good. Be sure to keep your ears covered. And a neck gator is best since it can't fall off.

I fluctuate between light wool to light silk or capilene or heavy wool/silk blend for sub zero. After that, whatever makes an insulation layer between the base and a shell will do. Ventilation is something to consider so you don't get wet. , My favorite ski outer jacket is a med. fleece with zippered vents that unzip most of the way down the under side of the sleeves. My favorite temps for skiing (Xcountry, any style) is 0F - +27F. I am not fond of fighting wind though.
