In the most extreme environments on Earth, trust is everything. Trust in your partner, your skill, and your gear. Mammut’s Eiger Extreme Nordwand 6.0 collection, developed with elite alpine athletes, is guided by Mammut's “Resourceful Performance” design philosophy — a no-compromise approach maximising performance whilst minimising impact on the planet.

 For Fall Winter 2025, Mammut and Pertex bring together their expertise in alpine mountaineering and fabric innovation to push the boundaries of what’s possible in gear built for extremes.

 “Thoughtfully designed layering systems, excellent heat regulation, and on-the-go repair features make the Eiger Extreme Nordwand 6.0 collection a system designed not only for performance, but also for responsibility—for the mountain, nature, and future generations.” – Mammut.

A key highlight of the collection is the Eiger Nordwand Pro Down IN Hooded Parka. An extra-warm, durable down expedition parka designed to provide maximum warmth for belays, bivouacs and extreme conditions.

The unique Pertex Quantum Pro outer fabric uses Diamond Fuse technology for the ultimate balance of weather protection, weight and durability. An ultralight 10D Pertex Quantum lining keeps weight and pack size to a minimum whilst allowing the 900-cuin down to loft fully.

Across the Eiger Nordwand Extreme 6.0 collection, Pertex and Mammut share a commitment to performance with purpose. From dope-dyed yarns that reduce water consumption, to recycled content, and repair-first design philosophies — these garments are engineered for longevity, not landfill.

Whether you’re climbing frozen faces, leading high alpine traverses, or guiding remote expeditions, this collection reaffirms one thing: the best gear doesn’t just perform in the mountains — it respects them too.
