Snow and extreme cold present one or two challenges for comfortable living that we in Britain are not traditionally very used to but it also opens up new opportunities and experiences for enterprising bushcrafters.
Northern cultures like the Saami, the Inuit and the First Nations have all thrived in extreme cold conditions for centuries and I often look to these for inspiration in my cold weather gear, with the addition of a few modern technical innovations where appropriate.
Layering is the best approach to insulation, rather than one or two thick warm items, try to build up multiple layers of thinner clothing that can be put on or taken off as you heat
up or cool down. You will generally need less insulation as you are moving and working than when you are stationary.
