Layering in the Pacific Northwest:

Knowing how to layer clothing will determine whether you are comfortable or uncomfortable in winter conditions. But be aware that the information here is for winter conditions of the Pacific Northwest, which are comparatively mild—meaning conditions between 0–45º F on average in elevations between 1000–7000 ft and winds that are mostly 0–25 mph and rarely up to gale force. You will likely need more insulation in colder regions, which is why in many places people are traveling on skis pulling heavier gear on a pulk, rather than backpacking in snowshoes. In Pacific Northwest, it is not difficult to backpack in winter with a 25–35 lb backpack. The mountainous terrain here would make pulling a pulk nearly impossible. Nevertheless, some of the basic techniques described in this short introduction to layering may be useful in other destinations.
