Off I go down to about 5F.
Colder than that, I add a Carhart jacket, put the hoody hood up and carhart jacket hood and I'm good to about -22F.
Colder than that.... I've never seen it. :confused3
I'm fortunate that I hardly ever get cold.
I'll go out to get the paper in my jammies and a hoody, barefoot in the snow down and back the 100' driveway sometimes, just to feel the ice on my feet. But gotta be careful. Bare feet in snow have little traction.
