15 years in the making and the Birth of the Cool Sweater has still got it. Crafted in Scotland from 100% locally sourced Shetland wool, the BOC is the byproduct of centuries of breeding in Scotland's harsh winter climate. Even more, this sweater's been brushed soft the old Scottish way—with a local, rough-fibered plant of the Honeysuckle family called teasels. Fine ribbing at the cuffs and hem further trap in the heat.
