Reddit mentions of Canari Cyclewear Women's Commuter Pro Shell Jacket, Clear, Small

I commute year round, and I've done it enough that I know how much to layer based on the forecast for the day. Here is what I use:

• on top, wicking layer topped by fleece jacket and a bright yellow windproof Canari shell jacket (which helps me be seen, too). If it's extra cold, add a middle layer.
  
• on bottom, long shorts or baselayer plus jeans/pants, with rain pants on top if precipitating.
  
• shoe covers over my commuter sandals, with wool socks underneath.
  
• balaclava under my helmet, with optional safety glasses if there is too much wind.
  
• Stratos split gloves with liners if it is very cold.
  
  Basically you want a wicking layer on bottom, a wind-resistant layer on top, and the middle can vary. Make sure your extremities (fingers and face) are well-covered.
  
  Also keep in mind that winter in Pittsburgh involves a lot of darkness or gray, sometimes all day long. Make sure you have good lighting (front and back), and the more reflective/glowy stuff, the better.
