Discover the Nigel Cabourn + Mammut collection – rooted in alpine expedition heritage, built for life on and off the mountain.

A blend of past and present

Together, iconic fashion designer Nigel Cabourn and Mammut present a unique unisex outerwear collection that honors Michiko Imai – the only woman on the legendary first ascent of the Japanese Direttissima on the Eiger’s north face in 1969.

Four winter outdoor scenes with people wearing Mammut snow gear, set against a bold red, mountain-themed backdrop.

Blending Cabourn’s deep-rooted passion for vintage craftsmanship and storytelling with Mammut’s alpine expertise in innovation and performance, the collection reimagines an authentic 1969 mountaineering kit through a modern lens.

Heritage fabrics + modern technologies

Featuring materials like Ventile® cotton, Scottish wool, and Swiss Army blanket fabric, the collection is warm and durable, with a timeless character. Paired with modern technologies like Pertex® Quantum lining and DRY DOWN, they perform to today’s highest standards.

The pursuit of authenticity

For over 50 years, Nigel Cabourn has defied fashion trends, crafting garments for the rugged world outside. What sets him apart is his ability to translate stories into garments that feel alive, speaking to resilience, adventure, and the human spirit.

Nigel told us, “It’s a real honor to do this collaboration, with Michiko Imai being the icon of it.”

Based in Northern England, Nigel draws inspiration from the cold, the wind, and the stories woven into every piece of heritage clothing he collects. Now, we’ve helped him capture a story close to our hearts, creating a collection that honors Michiko’s pioneering spirit.

A tribute to determination

  • The Direttissima, 1969

    A Japanese team completes the first ascent of the Eiger’s most direct and difficult route.

    The Eiger's north face with two climbing routes highlighted: a green zigzag path and a straight red line, as used by Mammut climbers.
  • Breaking barriers

    Among the six climbers was Michiko Imai – the first woman to summit the Eiger by this line.

  • A return to the Eiger

    At 83, Michiko returned with us to the Eiger to reflect on the climb that influenced her life.

A blend of past and present

This collaboration didn’t begin in a studio. It began above the treeline, on the Eiger North Face, Switzerland. In 1969, Michiko became the first woman to climb the Eiger via the Japanese Direttissima. Her story became the foundation of this collection.
