Japanese designer, Junya Watanabe, reimagines our mountain heritage through a distinctive design language, bringing alpine references into an unexpected new context.
This jacket features premium eiderdown. One of nature's rarest insulations in the world. It is hand-collected from wild northern eider duck nests after the ducklings have left. Incredibly soft and naturally lofty, Eiderdown delivers reliable warmth and temperature regulation whilst being lightweight. Made for long-lasting comfort.


Taking inspiration from our archive, this collection transforms iconic mountain references into a contemporary wardrobe – ranging from blazers and jackets to backpacks. This is Mammut quality, reconsidered for the worlds you live in.
