If cold weather bears down, take heart—or maybe revenge? The Revenge of the Hat fights back against the chill in insanely soft Scottish lambswool, which comes from the first shearing of the Merino sheep each spring. Plus it's been brushed the old Scottish way, using a local, rough-fibered plant called teasels for a pillowy finish. Like any solid wool, it's breathable by nature, with built-in odor control and a hint of stretch.
