The Canadian made some good points but he forgot the most impoartant part, which is moisture management. Any clothes that will hold moisture inside will ultimately kill you. No gore-tex and no down garments. Check the Wiggys website for clothes that work in extreme temperatures. Gear for oil field workers in Alaska to -60F. All made in the USA and cheaper than most overseas produced non-performing garbage. Another good source is european army surplus undergarments, like a coverall insulation etc. Dirt cheap and you will stay warm. Most of these will have correct moisture management ability.
