The Hardtack Sweater in Oak Donegal

Lightweight, luxuriously soft, and handsome as all get-out, this year's iteration of The Hardtack Sweater is slated to ship out just in time to beat back even the most ruthless coldfront. With its classic sheepskin elbow patches and beautifully understated donegal finish, The Hardtack is one of our all-time favorite autumnal layers. Like the changing colors of the leaves, we look forward to it every year.

Yak wool offers the same insulating properties and irresistible softness of cashmere—in fact, many argue that it's even softer—but it's more durable, offers better heat-retention, and it's sourced responsibly. Yaks thrive naturally with little food, and because they aren't confined to small plots of land like many other domesticated animals, their relative environmental impact is negligible. As they start shedding their plush undercoats in the springtime, the finest fibers are simply combed out and cleaned for use. Give those cashmere goats (and the land they graze) a well earned-break and say yes to yak.
