Offering premium protection against the elements and performance stretch and durability the Stoney HS Pants by Mammut are the ultimate all-mountain pants.

The Stoney HS Pants is the perfect choice for Eco-conscious snowsports enthusiasts seeking all-mountain performance.

Mammut completely redesigned the Stoney HS Pants to be the ultimate performance all-mountain snowsport pants and the most resourceful sports product possible – good for mountain users and the environment. The pants pattern is optimized to maximize the usage of Mammut’s 100% recycled high-performance mono-component hardshell fabric and reduce wastage to minimize its environmental impact.

"Our Stoney Outfit is my favorite all mountain snow sports set. Not only because of what we were able to achieve with the high performing recycled mono-component shell fabric, but also the resourceful approach we took in terms of pattern efficiency. When twinned with the timeless design, and all mountain feature set, alongside the build quality Mammut is renowned for, it makes for a hot piece for the cold season",
says Tim Ferm, Team Lead Product Management Apparel at Mammut.

The Stoney's Mammut Dry Tour shell fabric combines both resourcefulness and performance:  the fully recycled polyester mono-component 3-layer laminate provides enduring protection from the elements with 20.000mm HH and a 20.000 value in MVTR, which ensures that the comfort and inner climate of the pants remains optimal for the riders, however hard they push it. The pants construction also delivers unhindered movement, while Mammut has packed the Stoney with snowsports-specific features, including zipped ventilation to help riders regulate their personal climate; two velcro adjustments at the waist for a superior customizable fit; reinforced insteps making them abrasion resistant and durable; and integrated gaiters to keep the powder out.

Mammut is so convinced by the quality of the Stoney that they are even offering a 24-month warranty on them (12 months for professionals).

This Is What the Jury of the ISPO Award Says About Mammut’s Stoney HS Pants:

"Several small details in the cutting and manufacturing process that eliminate fabric waste, as well as the three-layer mono-component polyester fabric, make these ski pants a role model of resourcefulness."
