A second surge of cold air from the northern Polar Vortex has begun to make its way down across the Great Lakes region. It will continue to push toward the south and the east. That means, unfortunately, we cannot pack away our winter gear just yet. Layering provides protection from frigid temperatures. Innovations in textile technology have created a wide variety of fabrics and designs that improve heat retention and prevent penetration of the cold air to the skin.
The chart below describes the choices of available fibers, along with the benefits and drawbacks of each. It can serve as a helpful reference when you add new undergarments to your cold-weather gear. Avoid cotton undergarments, especially if you are expecting lots of snow or rain in your neighborhood. Underwear made with synthetic fibers, wool, or silk is moisture-wicking and transports perspiration and moisture away from the skin. These fabrics also dry much faster than cotton, reducing the risk of heat loss and hypothermia.

These undergarments look very fine and they are irresistible due to their fineness, I hope they will be as warm as they are fine
thanks for the chart – excellent info. I use thermals, merino wool or cashmere. can’t wear other wools…too itchy.
I definitely endorse merino wool which comes in different next-to-skin baselayer weights from micro to heavy. I use SmartWool and Icebreaker both of which are machine washable on delicate cycle.
Atsko SportWash is what I use for all my performance clothing.
Be sure to check for 100% Merino wool, as some will have only a small amount so they can “say” Merino. Just an FYI. Stay warm.
Thanks for the layering chart! I enjoy walking/running outside during Minnesota winters. Love the invigorating fresh air, but not the cold. The chart will help me figure out a combination that works for me. A timely post.
