Carhartt Bibs Temperature Carhartt Bibs Temperature Rating?

Carhartt bibs temperature rating? - carhartt bibs temperature

I'm trying to decide between the quilted lining Carhartt C02 and C03 Carhartt Arctic quilt lined bib and I asked myself the temperature rating for each. I go to his snowmobile in Wisconsin to use in a month, and I wonder whether the C02s would be warm enough.
