Stoney Hardshell Jacket

The Stoney Hardshell Jacket transitions from backcountry to resort just as smoothly as those fresh turns you just took. With a three-layer construction, it's thinner, more breathable, and longer-lasting compared to two-layer shells, and a welcome weight and bulk-level for touring. And of course the waterproof breathable DryTech membrane and fully taped seams keep you dry when it's snowing, be it on steep skins or chairlifts to the top.

  • Versatile ski jacket rides resort or backcountry comfortably
  • DryTech shell is ruggedly waterproof and comfortably breathable
  • Ventilation zippers under each sleeve amplify airflow
  • Removable powder skirt and hood customize coverage for any snow
  • Jacket-to-pant interface and thumbhole gaiters ensure a secure fit
  • Pockets for goggles, phones, ski passes, and more
  • Item #MAMU56I

For the price, not worth it

For a house made water repellent jacket, there is a lot lacking about this product. From a fit stand point, it hits the mark, and the color is stylish, but that's where the pros stop for me. Here are some quirks about the jacket where I ultimately felt it wasn't a good fit. - The draw cords on the hood and hem line were difficult to adjust - The hand warmers are a challenge to get in and out of - The pit zips were not easy to reach or adjust - It's a heavier coat when compared to some of the competition at the same price point Ultimately decided to return it. I typically where a L in coats, but based on sizing, I went up for an XL for layering purposes. I have broad shoulders and chest (44R blazer), and while it fit well, still some snug tugging on the arms and elbows. Would not recommend.

THis jacket has all the bells and whistles. The front pockets are big enough to stuff skins. Lining is plush for a shell. Thicker material, softer feel (doesn't sound like a plastic bag in the cold) makes it look and feel better than either of the Arcterrx shells I have. I highly recommend this shell. Sizes more like US sizes ((some Mammut sizes small ).

Mammut Stoney HS Jacket

I gave it as a gift but have feedback to share
True to size

I gave this as a gift to my brother in law and here is his feedback: The Mammut Jacket is the perfect ski jacket for me. It is light and comfy to wear so I can do anything I want on the slopes. It is not restricting at all. In three straight days in Vermont this year I wore it in the frigid cold, windy weather and also in the pouring rain - classic Vermont weather. Anyway, it was perfect in all of those conditions! I am very psyched with the coat and highly recommend it.
