The Men's Outdoor Research Chaos adds protection and insulation when conditions get out of control. A weather-resistant shell deflects snow and synthetic loft retains warmth. The deep hood and high collar seal out howling weather, whether you're wearing a helmet or not. It's sized as an over-layer, so it can go over what you're already wearing.
GREAT jacket
While not the warmest jacket on the market, it seems to hold it's own on Chicago's cold windy days. And you do not heat up indoors! It is designed for layering without sacrificing warmth. A generous interior pocket for gloves, hat, scarves and anything else you can think of stuffing in.
