The fisherman's sweater — Irish, Norwegian and the one from the Baltic

9 July 2026· The Handmade Heaven workshop

The fisherman’s sweater is one of the few pieces of clothing born purely out of need — and that’s exactly why it never goes out of fashion. Chunky sheep’s wool, a tight knit and no ornament without a function. Here’s the short history of a style we’ve been wearing for 150 years.

Where did the fisherman’s sweater come from?

The fishermen of northern Europe needed clothing that warms even when wet, stops the wind and doesn’t restrict movement while hauling in nets. The answer was sheep’s wool with the lanolin left in — a natural wax that repels water — and a dense, chunky knit worked on needles by the fishermen’s wives and mothers.

Irish, Norwegian, guernsey — what’s the difference?

• The Irish sweater (aran) — the best known: cream, undyed wool and raised cables. Legend has it that every family on the Aran Islands had its own arrangement of stitches. A lovely story, though historians are sceptical — above all, cables thicken the fabric and increase insulation.
• The Norwegian sweater — thinner, but knitted in colourwork: two-colour patterns (stars, snowflakes, the “lusekofte”) create a double layer of wool that warms even more.
• The guernsey (gansey) — the English forerunner: a very tight, plain knit with small patterns only at the yoke, almost windproof.
• And from the Baltic? Polish fishermen wore simple sweaters in raw sheep’s wool, in the natural colours of the fleece — no ornaments, but indestructible.

Why sheep’s wool, and not merino?

In a fisherman’s sweater, coarseness is a virtue. Chunky sheep’s wool stands up to friction and moisture better than delicate merino, and the lanolin gives it natural water repellence. It’s a sweater to wear over a shirt or a roll-neck, not on bare skin — and for special missions: sailing, mountains, campfires, an autumn walk along the shore.

The fisherman’s sweater today — women’s and men’s

These days the fisherman’s sweater is worn far from the trawler: oversized with jeans, classically under a waxed jacket, a women’s version with a coat. Our fisherman’s sweater “Bałtyk” is hand-knitted from undyed wool of Polish sheep — in natural white, brown and grey, in sizes M to XXL. And if you dream of a version with aran cables or a different colour — we’ll make it to order.
