Product Insights & Style Tips
The Mammut Stoney HS Thermo Pant makes cold days feel more like a ride than a grind. Built with Mammut's DRYtechnoly Pro two-layer membrane, they shrug off snow, wind, and slush while staying breathable for hard-charging laps. A PFC-free DWR finish adds eco-conscious water repellency, and lightweight Ajungilak OTI Element insulation delivers warmth without bulk. Thigh vents let you dump heat on climbs or bootpacks, and Cordura kick patches guard the edges.
An adjustable waistband and integrated snow gaiters keep the fit secure through deep powder days, while a relaxed silhouette leaves room for baselayers and a midlayer on the ascent. The face fabric blends 88% nylon and 12% spandex for easy movement, with a soft 57% polyester and 43% nylon lining. The 60g Ajungilak OTI Element insulation stays light on moves, and thigh vents open for cooling when needed. With 20000mm waterproof and 20000g/m2 breathability, you stay dry from lift line to descent.
Mammut keeps its alpine DNA front and center with a rugged, versatile silhouette that moves from powder fields to street style. Rugged Cordura kick patches echo the protection you need, while the PFC-free DWR and breathable two-layer shell balance sustainability with performance.

Recommended Care
- Machine wash cold on gentle cycle with a mild detergent; close all zippers and fastenings
- Do not use fabric softeners or bleach as they can degrade the membrane and DWR
- Tumble dry on low heat or line dry; drying helps restore insulation loft and DWR performance
- Avoid high heat; do not iron the fabric or the membrane; if needed, use a cool steamer away from the membrane
- Reproof the water repellency after washing with a DWR spray or wash-in treatment
- Store when completely dry, hanging or folded; keep away from heat sources to preserve insulation
