I have trouble in the very cold temps trying to get the clothing correct. I am good at wearing what works for riding, but that doesn't work for standing around fixing a flat. I have only a 5 mile commute, so now I'm throwing in an extra sweatshirt in my bag and will use my cell phone if I get a rear flat. I'll fix the front, but there is no way I'm going to be changing an IGH full chaincase rear in the dark at 5 degrees on the side of the road.
