How much does this jacket weigh?
The medium comes in at one pound, 11.2 ounces. The larger and smaller sizes will be right around that weight?
Can this hood fit a helmet?
Yes. The Stoney’s hood has enough space to fit a helmet inside comfortably.
How is the sizing?
While the Stoney’s fit is quite nice, it tends to be a bit small for larger skiers. You should size up.
Why Trust Me
I’ve been hitting the slopes since I was a kid. I enjoy getting out in the snow and have hands-on experience wearing a wide range of different ski jackets. I spent ample time analyzing this jacket’s traits and breaking down how it held up in both light and tough conditions.
Detailed Review of Mammut Stoney Jacket
The Stoney Jacket is a solid hardshell thanks to its excellent features, strong waterproofing, and flexible material. The item has a great feel and comes with top tier weather resistance, even if that does come at the cost of a heavy shell. It provides skiers with a lot of mobility and has the versatility to be used both on and off-piste. That makes it a good choice for skiers at all different ability levels.
Rather than going with the more traditional Gore-Tex waterproofing, the Stoney utilizes Mammut’s special DRYtechnology membrane. Though I’m always a bit skeptical when a company breaks from the mold, this holds up quite well in both harsh and light conditions. It’s comfortable in wet environments, especially because it’s backed by the DWR outer finish and full-taped seams. That all comes together to form a tight package.
Those traits are then backed by a cinchable hem, powder skirt, and rather tough hood. I found those features to work well with each other and offer some of the best weather protection money can buy. If I have one issue here, it’s the short collar and how susceptible the jacket can be to wind. The water resistance is solid, but this is definitely susceptible to biting breezes.
Comfort and Breathability
A big plus for me is the Stoney’s stretchable material. Mammut definitely made the jacket with mobility in mind. The stretchy build allows you to easily move and stretch. It also provides a nice fit that’s quite comfortable. This jacket feels great on your skin and actively promotes comfort in multiple ways.
Going off of that, the Stoney is also quite breathable. Ventilation is one aspect heavier jackets tend to struggle with, but you’ll get no such problems here. The pit zips allow you to both ski and hike with ease. Just know that you will experience worse weather protection with them open, which is an obvious-but-annoying trade-off.
Long Lasting and Well Made
The Stoney is a sturdy piece of clothing made to stand up to harsh winter weather. The fabric, while stretchy, has a toughness that I greatly appreciate. There are also some details built into the item, such as tough zipper pulls, that round out the general durability. This is a sturdy piece of clothing that will hang around for a good amount of time if you take care of it.
That being said, the Mammut Stoney is definitely on the heavier side. That extra weight makes sense for a stronger shell, but it also makes the Stoney much better suited for resort skiing than long backcountry treks. You might be able to use it on shorter journeys, but there are much better options for skiers who want to take long trips.
When it comes to extras, the Stoney excels. Not all of the features are as good as I initially hoped, but they more than get the job done. You get a large cinchable hood that can easily fit over a helmet and it’s removable as well. In addition, the three-point adjustment design is both secure and easy to use, even with gloves on.
I always appreciate pockets, and the Stoney comes with its fair share both inside and out. You get two hand pockets, dual chest pockets, a small pass pocket that sits on the left forearm, as well as an internal mesh pocket. That range enables you to store anything you might need. Add on the included removable powder skirt, and you truly get a strong jacket that freely adapts to your skiing style.
Price and Value
In terms of value, I give the Stoney mixed marks. It has plenty of fun features and does its job quite well. On top of that, it’s also reasonably durable and will last a decent amount of time. However, it costs a fair bit more than what some people may be willing (or able) to pay. If you need versatility and want to pay for quality, I’d say this is a decent purchase. Just know you can get away with similar jackets for a bit less.
What I Like
My favorite part of the Stoney Jacket is the comfort it provides. This jacket is stretchy, easy to move in, and utilizes a fleece material at the collar. All of that creates a trim fit that feels snug without being too tight or restrictive. Adding to that, the ventilation is also quite nice. I always appreciate when waterproof shells go out of their way to ensure you don’t overheat on the slopes.
The other big bonus for me is the different features. Not only do they help justify the Stoney’s higher price tag, but they give you a lot of extra versatility. The hood and powder skirt further the general protection, and they are both removable. That further increases your options. It’s also worth mentioning that the different pockets have plenty of room inside so you don’t have to worry about running out of room.
What I Dislike
In my opinion, the Stoney Jacket’s biggest drawback is the weight. At over one pound, it’s going to cause some fatigue over time. That’s especially true if you’re a backcountry skier who’s used to going on long or extended journeys. It’s much better for those who want to keep their trips short or who do most of their riding in bounds.
I think the weather protection could also be better. The Stoney does a lot to mitigate weather exposure, but the collar isn’t the snuggest and it tends to let wind in. The value could be better as well. This isn’t the most expensive jacket you’ll ever see, but it’s a pretty heavy investment. I would have expected a bit better construction for that price.
The Stoney Jacket delivers in a lot of areas, but it’s not perfect. If you want a similar-but-different model with unique traits, these are all worth a look:
- Hemispheres – If you’re looking for a similarly expensive jacket to the Stoney, the Hemispheres from Outdoor Research is a good way to go. This model gives you a lot of great features for the elevated price, including a breathable Gore-Tex fabric that stretches quite well, and a tough, helmet-compatible hood.
- Arc’teryx Sabre AR – This is another premium jacket with premium features. The Sabre AR (review) is one of the best-constructed options on the market. That, mixed with the breathability and weather protection, makes it an excellent freeride option. It has many solid features that both further the functionality and keep you protected in all conditions.
- Skyward II – Another good choice from Outdoor Research, the Skyward II (review) is a reliable, well-rounded hardshell perfect for those who want extra protection for their travels. While this isn’t the best in terms of flexibility, I’m a big fan of the 3-layer design. It’s also incredibly waterproof and comes in at a lower price point than other premium items.
Overall, the Stoney is a nice jacket that gives you a solid build and excellent traits at the cost of some protection. You’re also going to pay quite a bit for the design, but it can be worth it if you’re someone who wants a superior piece of clothing you can take around the resort. The jacket is both stylish and comfortable thanks to the flexible-but-durable material used in the construction, and it will last quite a while. That alone makes it a decent investment for those willing to pay more.
