you guys are funny.
OP, for winter commuting, get another bike, a beater bike. DH must understand it's about health and safety. We put one together for MY DH a couple years ago when he decided he wanted to ride in ANY weather. It did keep the snow away for the most part.
We bought him an old mountainbike (from the time when they just had regular bike frames) put on moustache handlebars, changed the saddle and pedals... and put on studded snowtires. much cheaper than a 4 wheel drive car!
