Recently we lucked out with a big stock of vintage Irish and Scottish sweaters with a mix of Fair Isle, Shetland, and British wool. All of them are that strong wool you'd expect from the northern isles and would make perfect layers to survive the harshest winters.
This compact Shetland sweater is great for a wintry day of golf in the Scottish countryside. What, that's not on your itinerary? Pretty small so could work for women as well.
