Took the dog out for it's morning {super quick} walk {dump and run} and it took me longer to dress than I was outside.
Longjohns, jeans and hunting pants, hunting boots that are good to -20, five layers and my "Chiller Killer" hunting coat, along with face coverings and great gloves, I was warm.
The dog was doubled layered with boots but sub-zero temperatures chase you indoors rather quickly.
Without wind, it's OK but if the wind kicks up to 10-15 mph, get inside if you can.
The wind - hate the wind.
