Mammut Stoney Hs Pant - Men's

Product Insights & Style Tips

The Mammut Stoney HS Pant channels rugged alpine ease with serious protection. A three-layer DRY Tour membrane keeps wet snow out and wind in check, while heat vents keep you from overheating on long descents. The face fabric is a durable 75D nylon blend with a touch of polyester and stretch, finishing with Cordura cuffs for durability. Lining is recycled polyester, and the whole package carries Bluesign Approved, recycled/repurposed credentials.

On the move, the stretch fabric follows your line for powder runs and side-country hikes without feeling restricted. Fully sealed seams lock out moisture, and the 20,000 mm waterproof rating plus 20,000 g/m2 breathability keep you balanced from first chair to late-day sun. Layering options are clean—a shell or midweight base sits neatly beneath, and the silhouette holds its shape through climbs, drops, and après without looking bulky.

Mammut sits at the crossroads of rugged performance and pared-back style. The Stoney HS Pant extends that ethos into backcountry-ready, everyday wear with a minimal line and technical confidence. Bluesign Approved, recycled/repurposed materials underline its responsible approach to outerwear while keeping the cool-girl ski-code intact.
