My coldest is 0F, -20F wind chill, at night with an 8 mile commute. It took me almost an hour to get home. The added warmth of my messenger bag on my back was welcome as it prevented some of the heat inside my jacket to not escape. Not sure how you don't use goggles Hypno Toad, there is no way I could ride those temps without eye protection. I picked up a set of Oakley snowboarding goggles and have had no issues with fogging unless I am looking directly down and breathing at the same time. While riding, they are fog free.
