As authentic and true to heritage as a heritage Shetland sweater gets - this version is brushed in the tradition of "shaggy dog" sweaters adopted by Ivy League trads in the US. Jamieson's is a rare, one-of-a-kind operation: the family breeds the sheep, collects the wool, spins the yarn and knits the sweaters - all on the Shetland island, half-way between the Scottish coast and Norway.
