I would like a pair of insulated pants that I would wear over a base layer. Ideally, the pants would be suitable for hiking, cross country skiing, downhill skiing and outdoor family fun. If I had to compromise it would be in the warmth of the pant, as I really want them to be comfortable for movement, and not too bulky. I can compromise by adding another base layer if needed. For use in temps down to about -15c (southern Ontario).
