What Our Gearhead® Experts Are Saying:"This jacket is all about warmth-to-weight efficiency. The 850-fill DRYDown insulation keeps me warm in extreme conditions, and the hydrophobic treatment ensures it still insulates when damp. I love the strategic synthetic insulation in high-wear areas, which adds durability where I need it most. It packs down small, making it an easy addition to my kit for ski touring, mountaineering, or cold-weather climbing."Designed for the demands of high-alpine adventures, the Mammut Taiss IN Hooded Jacket delivers exceptional warmth in an ultralight, packable design. Its 850-fill DRYDown insulation offers an unbeatable warmth-to-weight ratio while maintaining loft and performance in damp conditions. A durable, recycled nylon shell with a weather-resistant coating provides protection from wind and light moisture, ensuring we stay comfortable in unpredictable mountain weather.Strategically placed synthetic insulation in high-wear areas—such as the shoulders, forearms, and hood—adds durability and targeted warmth where it matters most. A helmet-compatible, adjustable hood and pre-shaped sleeves enhance mobility, while the two-way zipper and stowable design make this jacket a versatile companion for technical pursuits. Whether layering under a shell or wearing it solo, the Taiss IN Hooded Jacket is built for serious alpine performance.
