Never get stuck and never get out to help and the cold won’t be an issue!!
Actually I were Duluth trading fleece lined Duluthflex pants with light weight Smartwool long underwear they are water resistant. On top it’s also a light weight Smartwool and a med weight flannel shirt. I have a couple of jackets, a light water resistant soft shell, a carhart waterproof insulated work jacket and finally a fancy heavyweight down for looking good!
Snow gators are a good idea if the snow is deep.
I run the heat in the truck at about 66 so as not to over heat unless I have been outside for a while working a recovery and need a warm up. 7 of 8 years (missed one for a work issue) and I been good so far with this clothing choice but it is bordering on being overdressed.
