Question of the Day: Layer Up!

Snowmageddon has passed, the kids are back in school, and the temperatures are back in the double digits. I’ve actually been thinking about heading back out to check out the trail, now that the weather isn’t quite so…arctic. But that means lots and lots and lots of layers to stay warm.
When winter hits, how to you layer up? What are your go-to items of winter gear for those cold-day walks?
