The fisherman sweater has been around for more than a century. The now-timeless style originated in late 19th-century coastal Ireland before gaining global popularity in the 1950s after being featured in Vogue.

For a garment with such a long history, it has evolved surprisingly little — until now.

Premium outdoor brand Ibex, most known for its durable and versatile merino wool apparel, has reengineered the iconic knit sweater from the inside out.

It may look just like its traditional cozy counterparts, but the Nautilus Fisherman Sweater may mark the next step forward in technical sweaters.

High-tech fiber

Ibex’s latest release merges advanced material engineering with classic style, resulting in a hard-working layer that looks as good as it performs.

The standout feature of the new sweater is its use of Nuyarn technology, which wraps merino wool fibers around a high-performance nylon filament, allowing wool to perform at its peak and imbuing it with enhanced resilience.

The new knit is capable of five times faster drying and 85 percent more elasticity than standard merino, without the use of spandex.

The 70% merino wool/30% nylon blend offers better thermoregulation, faster drying times, 85% more elasticity than traditional merino and much higher durability and abrasion resistance than conventionally produced wool.

Old school style, new school tech

The Nautilus doesn’t just use innovative fibers to enhance a traditional style; it also employs very modern manufacturing methods.

The sweaters are made in Brooklyn, New York combining a classic 8-gauge, 2×2 rib knit aesthetic with the modern precision of bespoke 3D knitting.

This method isn’t just futuristic — it’s also more sustainable than old-school methods, because the final shape of the sweater is made right on the machine. That means no scraps, and little to no waste.

The 3D process also allows for some technical knitting design features. These include an open-knit structure in the underarms, boosting ventilation, and elbow pads with a more durable knit structure designed to increase longevity.

The sweaters are made to order thanks to their bespoke construction method, but the turnaround is still fairly quick, Once ordered, the men’s and women’s sweaters have a 6- to 9-day turnaround.

A new era of coziness?

Ibex has proved with its new Nautilus Fisherman Sweater that just because a style has been around for over a century doesn’t mean it can’t be improved upon with better materials and manufacturing.

Is this the start of a new era of innovative, technical lifestyle apparel that looks city ready, but can perform like your favorite outdoor gear? Only time will tell, but it sure looks like a promising start.
