Taiss IN Hooded Jacket delivers ultralight 850-fill down warmth with weather-resistant performance for alpine pursuits
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.

Great Jacket. Light and Warm!

Just wrapped up a trip to Lake Tahoe and finally put my Taiss IN Hooded Jacket to the test—temps ranged from the 20s to low 50s, and this thing held up beautifully. Definitely runs warmer than my ultralight down jackets, which was perfect for the alpine spring mix. I bought a Large and I like the European fit—it's not boxy, a bit more tailored. I snagged it on sale (50% off!), so value-wise it was a home run—but honestly, after wearing it, I’d consider paying full price. Only heads-up: it gets toasty fast when you're indoors—especially in airports or planes. Might be smart to bring a lighter layer for long travel days. Big thanks to Mammut and Backcountry. Solid gear.
