Men's Lightweight Hooded Down Jacket

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.

Also available as a gilet.

Reviews displayed include the earlier editions of the Fenrir. We’ve kept them here to showcase the Fenrir's legacy while introducing this new world-first version.

2 Fenrir's are Better Than 1

Pertex Quantum Pro is an upgrade on the original but otherwise the usual Jottnar quality with this, my 2nd Fenrir. Im 6ft and 70Kg, small works fine for me.

Excellence as standard

I don’t expect anything else from Jottnar now. A customer for life.
Super lightweight, looks slick too, not a bulky boxy duvet cover like the rest of the market. Top class as usual

Excellent!

Superb light weight jacket. Warm and fits really well, unlike some down jackets. Highly recommended.

Awesome!

Super happy with this. Very comfortable, lightweight and warm. Yes it's expensive but worth it due to the sheet quality. I also lo e the fact it's not a really well known brand so you don't see them everywhere. Can't fault it.
