On a recent journey to Iceland, I discovered 66° North. Named for the island’s Arctic latitude, this rugged outdoor clothing line is a favorite of Icelandic explorers, mountain guides and the Olympic ski team, competing in the 2010 Winter Games at Vancouver next month. While climbing around glaciers, riding horses in the highlands, and fishing on a long-line day boat off the Westfjords, I wore a black weatherproof Esja parka ($456). My first hoodie! So what if I looked like Kenny from "South Park"?

Lined with faux fur, it has also tested well back home at a mere 44° North, on the western edge of the Adirondacks in upstate New York, where the mercury drops to -20°F at night. That’s ice cold, baby.
