Tim,
I use the Sporthill XC for skiing climbing, and cycling. The are warm , durable, and dry quickly. They also block winds to to 35 mph. They are expensive, but I have one pair, which have seen a lot of use, that are at least 15 years old, and I still wear them. About 85% of the men and women in my ski patrol wear them. I also have a pair of what used to be their "Zone 2" pants that I use for cycling, and at the gym during cool/cold weather. Both pants pack reasonably well. Rolled up a size medium is about the size of a 22 oz. water bottle. Take a look at their catalog.
