eYe JUNYA WATANABE MAN + MAMMUT: A visionary interpretation of alpine heritage

Junya Watanabe, one of the most influential contemporary designers from Japan, unites with Mammut, one of the most respected mountain brands from Switzerland, for a special collaboration and capsule collection, reimagining alpine performance through a distinctly creative lens: eYe JUNYA WATANABE MAN + MAMMUT.

Mammut is proud to announce the launch of eYe JUNYA WATANABE MAN + MAMMUT, available from 24 September 2026. Bringing together Mammut’s heritage in alpine innovation and eYe JUNYA WATANABE MAN’s celebrated approach to design, the capsule collection explores the intersection of mountain culture, contemporary fashion, and everyday urban life.

More than a conventional collaboration, the project represents a unique creative exchange between two worlds. Inspired by Mammut’s archive and deep-rooted connection to the mountains, Junya Watanabe presents a collection that interprets Mammut’s iconic design language through his own visionary perspective, merging technical heritage with contemporary style and a uniquely Japanese approach to craftsmanship and reinvention.

"The collaboration reflects Mammut's ongoing commitment to exploring how mountain culture can inspire creativity far beyond the alpine environment." Heiko Schäfer, Chief Executive Officer, Mammut

The accompanying campaign, featuring a surprising CGI 3D animation, creates a dreamlike world where familiar urban elements appear within vast alpine landscapes. Escalators emerge above the tree line, elevators open onto mountain peaks, and everyday environments are transformed into unexpected gateways to Mammut’s world. The result is a visual narrative that reflects the spirit of the collaboration itself: a meeting of seemingly contrasting worlds united by curiosity, creativity, and a shared respect for design.

A journey of exploration and inspiration

The collaboration began with Junya Watanabe’s exploration of Mammut’s archive, where decades of alpine product development, technical innovation, and mountain heritage provided inspiration for a new creative interpretation.

Rather than simply borrowing visual cues, the collection immerses itself in Mammut’s history while reshaping it through the distinctive language of eYe JUNYA WATANABE MAN. The result is a collection designed for a new generation of consumers who move fluidly between urban environments and outdoor pursuits, carrying the spirit of the mountains wherever they go.

“This season, I wanted to create some pieces that combine the craftmanship and elegance of eYe JUNYA WATANABE MAN with the genuine alpine expertise and technical innovation of Mammut” Junya Watanabe, founder of eYe JUNYA WATANABE MAN

The Collection

The eYe JUNYA WATANABE MAN + Mammut collection comprises six jackets and one backpack, each reinterpreting Mammut's alpine heritage through Junya Watanabe's distinctive design lens.

Drawing inspiration from key pieces discovered within the Mammut archive, the collection transforms iconic Mammut product codes into elevated contemporary menswear. Technical outerwear silhouettes are revisited through refined material choices, considered detailing, and Junya Watanabe's signature approach to reconstruction and reinterpretation.

"For this collaboration, we invited Junya Watanabe to engage directly with Mammut's product heritage and reinterpret it through his own creative lens. The collection combines authentic mountain design elements, premium materials and functional details with a highly distinctive approach to construction, resulting in pieces that feel both rooted in Mammut's alpine DNA and entirely new in their expression." Paul Cosgrove, Chief Product Officer, Mammut

At the heart of the collection are six jackets that balance Mammut's functionality and mountain pedigree with a distinctly fashion-forward aesthetic. Highlights include a Ventile® jacket with a detachable hood, an insulated jacket featuring Junya Watanabe's signature patchwork detailing, and a luxurious eiderdown piece that combines one of nature's rarest insulations with refined contemporary design. The collection is completed by a minimalist backpack featuring a rope-inspired handle and a Mammut mascot attached via a climbing carabiner.

Designed for modern lifestyles rather than purely technical mountain use, the collection bridges urban environments and the spirit of alpine exploration. Each piece reflects a fascination with the mountains while remaining highly relevant to contemporary everyday wear.

The collaboration represents a dialogue between heritage and innovation, performance and expression, utility and creativity, viewed through the unique perspective of one of contemporary fashion's most influential designers.

The eYe JUNYA WATANABE MAN + MAMMUT collection launches globally on 24 September 2026 on selected Mammut channels and premium retail partners.
