Despite the Nordic name, Jöttnar is a British brand that is actually a relatively new kid on the block in terms of outdoor kit. However, it has quickly built a reputation for turning out some of the finest technical apparel in the business, epitomised by the handsome Jöttnar Fenrir down jacket. This midweight hooded down coat uses premium materials, including 850-fill-power water-repellent goose down and a 30-denier ripstop nylon face fabric. It also employs synthetic insulation in moisture-prone areas like the neck, hem and cuffs, which when put together with that hydrophobic down fill, makes this a more versatile and weather-resistant down jacket than most.

In the Field
We were immediately impressed with the Fenrir’s superb warmth for weight, which makes it a brilliant throw-on layer for hiking, hillwalking and general mountain pursuits. Yet despite its light and packable nature it doesn’t sacrifice features. So, you get a full-length zip with an inner baffle, plus twin zipped hand pockets and an internal zipped security pocket. There are anti-snag drawcords at the hem, stretch cuffs that fit easily over gloves and an elastic-bound hood, with a rear cinch cord.
The fit is absolutely spot on, which is particularly impressive, as baffled down jackets are notoriously hard to tailor well whilst maximising thermal efficiency, without adversely affecting overall comfort and freedom of movement. We think this jacket really comes into its own as an extra layer for winter summit trips or chilly wild camps. It is certainly capable enough to be used for more technical climbing and mountaineering too, though a couple of shortcomings – namely, a hood that doesn’t quite fit over a climbing helmet, and a main zip that has only a single zip puller – make it slightly less well suited to these pursuits.

He’s based in Snowdonia and last year thru-hiked the Cambrian Way, which runs for 298 miles from Cardiff to Conwy, with a total ascent of 73,700 feet – that’s nearly 2½ times the height of Everest.
