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.

Fenrir Is 5 star !

I am very happy with my purchase of the Fenrir Jacket. I was looking for something that was smart but compact and able to keep me warm without wearing lots of layers underneath. The jacket is very high quality as you'd expect from this brand and does not disappoint. The customer service team were brilliant pre sale and advised they could post out next day. I would 100% recommend this product. I wore it on a recent trip to Scotland at winter time and only wore a t shirt underneath where the temperatures were single figures and I did not feel cold at all. I purchased a large size and have a 34in waist and 42in chest, 5ft 10 medium build.
I won't hesitate to purchase more from this brand. Thank you.

Men’s Jottnar Fenrir Large

I am like the Jottnar founders ex military, and over the years I have purchased and worn a number of different brands of jackets, but this feels superior. Very professional setup, from the outset instant and helpful email. I ordered on the Friday and I was kept informed from the outset, delivered two days later on the Sunday, while Evri gets some bad press , I also found them very professional, Morgan was very helpful. For the record on size which was my only concern, I am 12 stone 7Ib , 5.ft 11in, 44 inch chest 16inch neck , slim gym goer and the large fits perfectly. Very pleased. Would thoroughly recommend.

Outstanding quality

Ordered size Large as I take Large in everything and already own a jottnar coat in large . Unfortunately the large , although fits perfectly everywhere else was slightly tight under the arms when i reached out so had to return it . Tried XL but looked too big , was so disappointed as the quality looks absolutely amazing and really wanted one . Not sure why it was tight under the arms though . If fitted would give a 5.

Fantastic jacket, bought the forest green. It has a lovely soft feel to the outer. It’s compact with good detailing. Originally bought the medium it was a bit too small returned it for a large so much better. Great customer service very quick and easy.

Nice up grade

Bought the newest version to replace the one I have had for many years. Same size(XL) I feel it’s very slightly a roomier fit, in the body and more snug around the neck head area which for me is a positive comment, also more warmer feel when wearing. I can not comment about how waterproof it is yet .( which was a problem with the last model)
Overall pleased with the purchase.
