I think I have found the temperature limit for the wardrobe currently in my possession. With the wind chill it was -23 degrees Celsius for my ride into work this morning and that was a head wind. I was quite cold and had a difficult time shifting my frozen bike. I had to avoid the side streets because they still have not bothered to plow them. I would be dancing in the street if the temperature were 35 degrees Fahrenheit, the snow melts at that temperature.
