Moving to a colder climate
Short answer: Build a layering system with a thin layer against the skin, an insulating layer and a windproof outer layer. It is the number of layers, not the thickness, that makes the difference in cold.
What changes
In a colder climate clothing is worn in more layers, and the layer against the skin becomes more important than ever before. That is where moisture needs to leave the body, because getting damp in cold means getting cold and uncomfortable quickly.
The innermost layer
A thin layer of bamboo viscose or wool moves moisture away from the skin effectively. It has to sit close to the body and stay thin, not thick, or it will not work as intended. See bamboo undershirts for men.
The other two layers
The middle layer holds air and warms the body over time. The outer layer stops wind and rain from getting through. Without that outer layer, warmth from the middle layer disappears quickly in wind. See sweat clothing and bamboo hoodies for men.
How many layers are enough
Three layers cover most conditions in a cold climate without making you sweaty indoors. More layers than that often squeeze air out of the system and actually warm less, not more, than three did.
Feet and hands
Feet and hands often get cold first, because blood is pulled toward the body's core in cold weather. Two thin layers of socks often keep you warmer than one thick pair, if the shoe has room for both.
Face and neck
Wind against bare skin feels colder than the actual temperature suggests. A flexible neck gaiter or a thin scarf protects the spot where warmth otherwise escapes the body fastest during winter.
Washing and caring for wool layers
Wool and bamboo viscose do not handle hot washing or the tumble dryer well. Wash cold and lay flat to dry, so the layers keep their shape and ability to move moisture much longer.
Indoors versus outdoors
The same layering system rarely works equally well indoors and outdoors. Take the outer layer off indoors so you do not sweat unnecessarily, and put it back on as soon as you step into the cold.
When cold becomes a health question
Most people adjust to a colder climate over time with the right layers. With persistent cold in fingers or toes, or if the skin turns white and numb, talk to your doctor about it.
Frequently asked questions
How many layers should you have
Three cover most conditions in a cold climate without being too warm indoors. Four layers squeeze air out of the system and so warm less, not more, than three do.
Can bamboo viscose be used in cold weather
Yes, as the innermost layer that sits close to the skin and moves moisture away. For actual warmth you need wool or fleece on top, since bamboo viscose alone does not insulate enough.
What about socks
Two thin layers often keep you warmer than one thick pair, if the shoe has room for it. Squeeze the foot too tight and blood flow drops, so feet get cold faster anyway.
