Jöttnar Hodr £535

Jöttnar’s latest flagship mountain shell utilises the brand’s own membrane, called Skjoldr. Older Jöttnar jackets used Polartec NeoShell, which was acclaimed for breathability but perhaps less so for its long-term durability.

Lab test results for Skjoldr indicate solid performance of 20k/20k Hydrostatic Head and Moisture Vapour Transmission Rate (MVTR). The membrane is bonded to a burly 80D nylon face fabric and protected by a heavyduty backer for exceptional durability. It’s a real workhorse that still feels soft and supple.

The fit leaves ample room for winter layers, while the pronounced drop tail and long arms provide plenty of coverage, even when bending over or stretching upwards. The Hodr also has one of the best hood designs we’ve tested, whether worn with or without a helmet. It cinches in superbly, with a broad, wired peak to deflect rain away from the face. Cutaway side sections give a wide fieldof-vision, while the top of the jacket zips right up to the nose for maximum protection.

Inside you get a zipped security pocket and huge stretch mesh dump pocket. The latter is a great place to stash gloves.

If you’re after fortress-like protection from the elements, this jacket is top of the pile.

IF WE’RE BEING FUSSY

We found the arms ever so slightly baggy. Other jackets here are lighter and felt marginally more breathable, though none are as tough as this. But it is very expensive.
