Finding the perfect winter outfit is like hunting for Bigfoot, UFOs, or little leprechauns. Some think they exist, but good luck finding one. Granted, those of us who have been through a winter or two know a bit about how to stay comfortable in the winter but I would bet if you asked any one of us we'd probably say it could be better. That's partially because of the limits of the human body and the technology of the materials we're covering ourselves with. Point is- you'll sweat if you do any moderate level of pedal pushing in winter. The key is how to stay comfortable, not focus on staying dry.
Doug and Jill have both done a recent "What I wore today" post and they each have very different takes on what gets the job done. I've done them in the past too and still to this day feel I could be more comfortable on my rides.
So, I'm going to start a new line of posts over the next few days. Rather then dressing how I normally do now I'm going to try several different things to see what works and what doesn't. Right now I'm trying to see if I can distinguish between a polypropylene and a polyester base layer. Tomorrow I'm going wool for the base. It's not really cold out yet so it's not all that accurate. After all, here in northeast MN we spend more time in winter like conditions then we do in summer like so I've got plenty of opportunity to be riding in the cold as the temps take their annual nose dive.
Stay tuned to see what conclusions I come to- it will be sort of "MythBuster" like. "Remember, don't try this at home, I'm (we're) what you call professional('s)".
