Today was my first commute below 0F (-3). It was the first time my legs didn't warm up immediately once I started moving (I wear only jeans). I had on a face mask and a balaclava, but I had to take off the balaclava because my glasses got fogged up and wouldn't clear up. You know how you get a painful tingling in an extremity that gets cold once you begin to warm up? Well, that happened to my nose today, for the first time.
