My annual reminder about these three essential items for a comfortable winter:

1. Ice cleats. I would never leave home without these.
2. Neckwarmer. A cold neck makes everything feel cold.
3. Good wool socks . I like Smartwool, but Darn Tough are also great if you have narrower feet than mine. Yes they're stupidly expensive, but they keep your feet amazingly warm even if a little wet. I wear these Hike Light Cushion Crew Socks in hiking boots (GORE-TEX, but uninsulated), and my feet generally stay plenty warm.
