I'm moving to Chicago and February, will be living downtown, and will have a 15 minute walk to work. What is an appropriate, yet warm enough, coat to wear to work? I work at an accounting firm and wear business casual. Don't want to get into sweaters I have a full length RL wool/cashmere coat, but it just isn't warm enough for when it is really windy and below 30. I was thinking about a down filled coat from Patagonia or Mountain Hardwear, such as these: http://www.zappos.com/patagonia-mens...n-jacket-black http://www.zappos.com/product/7645331/color/3 What do you think about these options? Any other suggestions? Thanks!!
