Eigerjoch IN Hybrid Insulated Jacket

In-bounds, off-piste, backcountry, about town—everyone knows you get around, and you do so at a quick pace. When you want to stay warm but let that active body breath, you pop on your Women's Mammut Eigerjoch IN Hybrid Insulated Jacket. Constructed with Quantum Air material, this soft little layer is super lightweight and breathable so you can traverse about and sidestep at the resort, step up your skinning game while you tour, and set a brisk pace to the bar post-skiing. You can even take this jacket ice climbing thanks to plenty of mobility technology incorporated into its design, with pockets strategically placed for harness-equipped access. If any snow should soak through the water-repellent face fabric, you'll still stay toasty warm thanks to the natural lofty qualities of synthetic down.

I use this jacket for ice climbing. It’s superb at regulating temperatures, and stays pretty warm. It also dries really quickly if you start to sweat in it. Good water resistance on the outside, even bled a bunch on it and it wiped off easily with some snow.

Love everything about this jacket. It's very light and flexible, but still manages to keep you warm and dry. I tend to run cooler than most people, so I was hesitant that this jacket would be warm enough for me, but it's been fantastic at keeping me warm by itself, or layering for extra warmth on those cold days. They also nailed the amazing purple color!


Up to what temperature will this keep you warm for light activity?

Hi Dawn, A lot of factors affect how warm you'll be in this jacket, including the level of activity you're doing, humidity, and the other clothing you're wearing. That said, this jacket is not intended for very cold temperatures. If you're looking for something to protect your from extreme temperatures, I recommend getting a down jacket at around 800 fill.
