Excellent tips and very well written article.
Having lived in the arctics for 10 years, most things winter becomes second nature.
In terms of clothing, do what the inuits do in Northern Greenland.
Hunting trips on dogsleds for weeks in the deep of winter in temperatures below -40C and sleeping in tents is quite common.
I have travelled with them on several trips and it works, but you do look unusual
Personally i prefer the arctic expedition boots from sorell when you are out for multiple days in temperatures below -30C, but go far enough north and the locals swear by their lamb and mosk ox wool linned seal skin boots.
Ohh and this is what you look like in the morning, when you realise it is -32C just outside of your sleeping bag
