A year-round alpine workhorse. Thorne is a relentlessly capable deep-baffled jacket engineered to endure the daily punishment of winter. Filled with 750 Fill Power hydrophobic goose down, fully extended into the hood for full-coverage warmth. It packs down light yet is a powerhouse piece for ski touring, winter trekking, and alpine climbing.

The premium 90/10 down/feather ratio powers impressive heat retention. 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.

This new evolution sharpens its edge: lighter, warmer, and cut from recycled OceanCycle Pertex® Quantum. A 50D micro ripstop, 100% recycled polyester that forms a tough barrier around the down. Ultralight, windproof, and water-resistant, Quantum fabric maximises down loft for uncompromising warmth while shrugging off snow, wind chill, and sudden showers. A PFC-free DWR finish adds further defence.

Concealed technical stretch cuffs, anti-snag hem adjusters, and a rear-cinched hood lock in warmth. Insulated hand warmer pockets, an external chest pocket, and a zipped internal valuables pocket provide functional storage on the move. A stuff sack keeps it pack-ready.

Thorne is the jacket you live in for the cold and chaos of deep winter.

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