Synonymous with warmth, wool has earned this well-deserved reputation for good reason—it’s cozy as hell. But don’t ask us, ask the submariners throughout history who depended on it to keep out the chill of relentless sea winds. Heimat channels this rich legacy in its Rolkragen sweater, knitted and hand-finished in Germany from extra-long fibers. Highly resistant to pilling, this 5-gauge knit will hold its shape for years of wear to come. And since the wool’s natural oils help retain its self-cleaning and water-resistant properties, your sweater will spend more time on the high seas and less in the laundry.
