A Decade of Refinement. Now a World-First.

The very first of its kind; a highly technical goose down jacket and world's first to feature expedition-grade Pertex® Quantum Pro outer fabric crafted from NetPlus® — 100% recycled fishing nets, fully traceable to their source. This tough, innovative, water-resistant fabric makes this Fenrir our most durable yet. Delivering positive impact while upholding a decade-long legacy of exceptional cold-weather performance, unrivalled build quality, and an outstanding review pedigree.

The Fenrir boasts our optimum warmth-to-weight balance and 850 Fill Power DownTek™ hydrophobic down with a premium 93/7 down/feather ratio, the highest practically possible. DownTek™ down stays dry 10x longer and dries 3x quicker than standard down. Our ethical approach complies with the Responsible Down Standard, and our hydrophobic down uses bluesign®-approved clean chemistry for its water repellent treatment.

Synthetic fill placement optimised for neck and cuff moisture zones enhance performance. Jöttnar’s signature no-snag hem cords reduce risk of gear tangling. Technical stretch cuffs allow bulky gloves to be worn. A highly compressible package complete with separate stuff sack, that excels as both a midlayer and outer.
