Our Donegal Tweed Fair Isle Crewneck Jumper, in a lambswool-polyamide-linen-yak blend, features a classic crewneck style, a traditional Fair Isle pattern a leather GANT label near the bottom hem and a super soft hand feel thanks to the natural fibers from the yak, a long-haired animal native to Central Asia. (Style side note: Donegal tweed, as originally woven in County Donegal in Ireland, is characterized by its colorful flecks, which are randomly distributed across a garment.)
