Screw that, I'd rather have snow than summer heat. When I ride in winter I dress in layers and stick to natural fabrics like wool because they work better at regulating body temperature. So called 'performance' fabrics are nothing but fancy plastic and when you're generating heat and moisture in a cold environment, that's where synthetics fail. Riding in fresh snow is pretty simple but is a whole different ballgame once it's packed or eventually becomes ice... stay in the loose snow as much as possible. I just run regular street tires because I live in a city where streets are plowed and treated so studded tires are rarely needed. Of course fenders are a must... the tires will sling sleet everywhere.
