When I look for winter pants I think of two words, "waterproof" and "hardshell." Some of you (probably people who only ski powder, don't break trail or are too hardcore to use their tools on ice) will disagree. That it is fine, wear your softshells all you want. But I want pants that will keep me dry when kneeling against melting ice, breaking trail in heavy snow or on a multi-day trip. I also want a single pair of pants that I can comfortably climb, skin, ski, hike and, occasionally, toboggan in.
