Today I got to test the car's new Hakkapaliitas in the slush, snow, and ice and would say it hooks up nearly as well as my bike does in this kind of weather...
Being that I had fired up the car I ran some longer errands and picked up a new winter / work jacket as synthetics don't work too well when you spend your day with a torch in your hand... there is nothing like canvas for that unless you need some Nomex.
