Shetland Wool has been keeping fishermen and farmers warm in frigid climates for centuries. Now, with this sweater, it's your turn. It's knit in a tapered fit for a more modern look than traditional wool sweaters, but without sacrificing any insulation. It's heavy enough to wear on its own over a shirt on brisk days, and when the temperature dips below freezing, it'll be right at home under a good jacket. We also recommend dressing it up with a blazer for some vintage professorial vibes.
