The Mammut Eigerjoch Advanced Insulated Hooded Jacket Men is a down-filled hooded jacket designed for active use in chilly conditions. It’s meant to keep you warm and comfortable during outdoor pursuits, from hiking and climbing to everyday cold‐weather wear.
Built with a lightweight 10D polyamide shell and filled with 90% down and 10% feathers, this regular‐fit jacket balances warmth and freedom of movement. It combines PrimaLoft® Gold synthetic insulation with Mammut’s 850 cuin down for reliable loft and heat retention even when damp. A PFC-free durable water-repellent (DWR) coating and HyperDRY™ treatment help shed moisture, while Pertex® Diamond Shield and Pertex® Quantum fabrics add durability without extra bulk. Fair Wear certification and responsibly sourced materials underline Mammut’s commitment to sustainability.
The 850 cuin rating refers to fill power, a measure of down’s loft and insulating performance—higher values mean more warmth for less weight. PrimaLoft® Gold insulation mimics natural down while retaining insulating ability when wet, and Pertex® fabrics are tightly woven to block wind and resist light rain. Together, these technologies ensure the jacket stays warm, breathable, and protective in a variety of weather conditions.

Mammut says about theEigerjoch Advanced Insulated Hooded Jacket Men
The Eigerjoch Advanced always keeps you warm without weighing you down. The insulated jacket works well as a mid or outer layer. It’s filled with a blend of two types of insulation to offer the perfect balance of warmth and moisture wicking: premium water-repellant goose down from Responsible Down Standard suppliers keeps your upper arms, core and hood interior nice and warm. The exposed and high-perspiration spots, such as the shoulders, hood, back and underarm sections are made with soft, stretchy PrimaLoft® Gold Insulation Active™ synthetic fiber material. The synthetic insulation also keeps you warm when the weather takes a turn for the worst or during more aerobic stages. The Eigerjoch Advanced jacket emerges unscathed after scuffles with rock and also holds up well to heavy backpacks thanks to its extra abrasion-resistant Pertex® Quantum outer material. Innovative and uncompromising. A light, technical down jacket for a wide range of mountaineering adventures.
