What Our Gearhead® Experts Are Saying: "These pants are a perfect mix of warmth and performance. The insulation is just enough to keep me cozy on frigid days without overheating, and the DRYtechnology Pro shell keeps me bone dry in heavy snow. I especially love the thigh vents for dumping heat on warmer laps, and the waist adjusters make dialing in the fit super easy."When the mercury drops but the powder is calling, the Mammut Stoney HS Thermo Pant keeps us warm, dry, and riding in comfort all day long. Built with Mammut’s DRYtechnology Pro two-layer membrane, these pants shield us from snow, wind, and slush while allowing breathability for hard-charging laps. A PFC-free DWR finish adds another layer of eco-conscious water repellency.Lightweight Ajungilak OTI Element synthetic insulation provides reliable warmth without weighing us down, making these pants perfect for single-digit days on the mountain. Thigh vents let us release heat when we’re bootpacking or hiking to fresh stashes, while reinforced Cordura kick patches protect against sharp ski edges and crampon scuffs. An adjustable waistband and integrated snow gaiters complete the design, ensuring a secure fit and full protection through deep powder runs and long chairlift rides.
