I use Sporthill XC pants. Which once again. Are heavy duty cold weather loose fitting pants that I wear alone from 45f to 15f.
I'll second his comment. I use the sporthill XC for skiing and cycling. I also have another pair of heavier Sporthill's that I use for really cold weather. I ride every day and rode when the temps were down in the low teens a few weeks ago. My wife commutes a couple of days a week year around and swears by her Sporthills. We also have several tops made by them. They are a local Oreon company, and we can pick up things at their annual sale. Sporthill products are a little on the spendy side, but in this case you truely get what you pay for.
