Earlier quoted context omitted.
Not all. I just put on my balaklava and some knobby tires. It's not that bad with the right clothes. I wouldn't walk around in Boston winter without my face masks either.
I'm genuinely curious: do you wear glasses? How do you keep them from getting fogged up/iced over when riding in the winter?
Also, my Asian nose doesn't hold glasses very well. Once while biking in the summer (with sweat dripping) they fell off in traffic. I was basically blind. It was terrifying.
Thus, contacts.
