This jacket should be good for well below zero with proper layering and the use of a knit hat. The duck material and quilted lining can keep the winds of Old Man Winter at bay. Two things that bear mentioning are Carhartt sizing in the jacket runs large and the front slash pochets aren't insulated, just the duck material between your hands and the weather. If you can find one to try on locally first, I would. Otherwise I'd probably order one size smaller than your usual. I did (an L instead of an XL) and it fits like a glove with room for layering. CampSaver got it out quickly too. A+ transaction all around.
