The Stoney Hardshell Thermo Jacket Men by Mammut is a versatile outdoor coat designed to keep you warm and dry on the mountain. Built for ski touring and rainy expeditions alike, this jacket combines insulation and a waterproof shell in one package, so you can focus on the trail ahead.
Made from a blend of 88% polyamide and 12% spandex, the jacket offers a bit of stretch for ease of movement, while its Regular Fit ensures room for layering without feeling bulky. Inside, Ajungilak® OTI Element insulation holds in your body heat when temperatures drop, and the Mammut DRYtechnology™ Pro membrane sheds moisture from both rain and snow. On top of that, the PFC-free DWR finish lets water bead off the fabric, and Bluesign® approval and Fair Wear certification reflect Mammut’s effort to reduce environmental impact.
Ajungilak® OTI Element is a synthetic insulation that mimics down’s warmth retention but still performs when damp, and Mammut DRYtechnology™ Pro is a microporous membrane that blocks water from the outside while allowing sweat to escape. The PFC-free DWR coating provides an extra layer of water repellency without relying on hazardous chemicals. Weighing just over a kilo, this jacket strikes a balance between protection and packability for long days in unpredictable conditions.
