First impressions

Jöttnar’s outdoor pieces are designed with mountaineers in mind and named after mighty Norse gods – and the tough Jöttnar Fenrir (a mythological wolf) is one of the brand’s standout down jackets for women (although, for some reason, it’s not been designed to be quite as warm as the men’s equivalent, the Fjorm).

Body-mapped and designed specifically for the female form, the Fenrir is stuffed with 850-fill goose down (which, happily, meets the Responsible Down Standard). The ratio of down to feathers is an impressive 93/7, promising excellent warmth-to-weight performance. The goose down has also been treated, so it is far more water-repellent than standard down fill.

In the field

We tested the Jöttnar Fenrir over a year of hiking escapades and mountain adventures, and found ourselves reaching for this versatile mid-layer again and again – it’s lightweight and very packable, squishing down into its own stuff sack for easy transportation, but offers fantastic warmth.

The Fenrir works both as a mid-layer under a waterproof shell, and as an outer jacket on cold but dry days. The fit is perfect – the jacket is not restrictive anywhere, and it allows good freedom of movement. An adjustable hood keeps your face and head cosy and stays put in wind, and a dropback hem warms the lower back and stays in place when the Fenrir is worn with a backpack. The outer material is also water-resistant enough to bead off light rain, and the treated fill performs reasonably well in light showers.

We wore the Fenrir while hiking in Chile and loved how easy it was to wear alone as an outer jacket, and that it fits under a waterproof on colder days. It’s also a comfortingly warm choice for cold-weather camping. The three dark blue and black colorways are smart and easy to wear just about anywhere. This quiver-of-one down may be expensive but it’s well worth the spend if you get outside all winter long.
