Mammut redesigned its best-selling Stoney HS Pant to better serve powder hounds in their pursuit of unspoiled stashes hidden in back bowls and dense forests. The reliable 3-layer DRY Tour membrane keeps wet snow from sending us back to the lodge early in the day while allowing excess heat to escape and blocking frigid blasts of wind. The stretchy material allows us to move naturally on our skis, giving us the freedom to ski our hardest down steep couloirs and on side-country slopes.
