Men's All-Mountain Goose Down Jacket

MOUNTAIN DURABLE. WARM & RELENTLESSLY RELIABLE

Built for the cold, and relentlessly reliable. The new, deep-baffled Thorne now features Pertex® Quantum—a superlight, windproof, and water-resistant outer fabric that maximises down loft for heightened warmth and comfort. Its DWR finish sheds light rain and snow to provide extra protection.

Relentlessly capable, this hard-wearing goose down jacket is designed for multi-activity use in cold and rough conditions. A refined balance of durability, comfort, and versatility makes it a powerhouse on and off the mountain. With a remarkable warmth-to-weight ratio, 750 Fill Power goose down, and a premium 90/10 down-to-feather ratio, it'll quickly become your go-to layer for everyday cold-weather adventure.

Our DownTek™ hydrophobic goose down stays dry 10x longer and dries 3x quicker than standard down, reducing fear of exposure in changeable conditions and will never wash out.

Feature rich: Body-mapped synthetic insulation is positioned in potential moisture zones at the chin, cuffs and hood. Concealed technical cuffs, hand warmer pockets with front facing insulation, articulated sleeves, reverse coil zippers, Jöttnar’s signature no-snag hem cords, and a stuff sack for its lightweight carriage.

Our ethical approach complies with the Responsible Down Standard, and our hydrophobic down uses bluesign®-approved clean chemistry for its water repellency treatment.

Reviews displayed include the earlier editions of the Thorne. We’ve kept them here to showcase the Thorne legacy while introducing the new 2025 version; further refined and improved.

Great quality

This jacket exceeded my expectations - warm but not bulky, stylish and comfortable.

Top class jacket

I took the chance to give this jacket a proper test through the recent wintery conditions.

The fit is quite close so I only wear it over a baselayer , that combo is sufficient to create a very comfortable envelope of warmth.

In addition the outer fabric has proved to be windproof and the generous coating of DWR promises some resistance to light rain.

Fast becoming an all time favourite, well done Jottnar

Superb "Goldilocks" down jacket

I received my Thorne jacket just prior to a spell of very cold weather arriving in Aberdeenshire, so it was put to good use pretty much straight away. As with other Jottnar products I own, it's put together superbly and with genuine craft, the areas with synthetic fill are precisely where other down jackets I've owned have had clumping of down or wetting previously.

I run fairly warm and find that at temperatures from -7 C up to freezing in light or no wind the Thorne is perfect for moderate exercise or for standing/sitting at a camp. I'm a firm believer that one of the keys to staying warm in the outdoors is not overheating and the Thorne is proving to be a "Goldilocks" jacket - not so over-warm that it loses some versatility while being warm enough to cover a lot of bases for Scottish winter conditions.

The attention to detail is superb and the design and fit are bang-on for me (Medium jacket size and I'm 5ft 8ins, 42ins chest, 32ins waist). I was curious to see how the toughened face fabric looked and felt, and I'm impressed. It's so much more robust than any other down jacket face fabric I've used, but crucially, isn't armour plated - again a great feature and I expect this jacket to last.

At a freezing bikepacking camp with temperatures approaching minus double digits, pulling on the Thorne was instant warmth and comfort, it's truly a "daily driver".

Jottnar kit may not the cheapest, but it's a premium price for a very good reason!
