The Y-3 shell pants from The Mountain Studio are engineered for demanding days on the mountain, whether skiing or snowboarding. Built with a rugged 3-layer ALP-3 mini ripstop fabric, these mountain ski pants deliver reliable waterproof protection and wind resistance, keeping you dry and comfortable in harsh winter conditions. The stretch construction ensures freedom of movement across varied terrain, while fully taped seams and a 20,000mm waterproof rating provide dependable weatherproofness for alpine touring and backcountry adventures.

Performance features are designed for real use in winter sports. Large side ventilation zippers allow quick airflow adjustments on steep climbs or warmer descents. Cordura leg reinforcements protect against edge cuts and abrasion, extending the life of these durable ski pants for winter sports. The ergonomic insulated insert at the back waistband adds targeted warmth and comfort, while the crotch gusset and articulated knees support natural movement. Elastic snow gaiters with silicone grippers seal out snow and wind, making these functional ski trousers with pockets a reliable choice for active use.

Minimalist design meets practical versatility, with clean lines and a refined silhouette suited for both mountain and city environments. The Y-3 is available in black and beige, offering options for a classic or two-tone look. Adjustable waist tabs and waterproof YKK Aquaguard zippers add to the technical ski clothing appeal, while pocket placement is optimized for easy access during skiing or skitouring. These lightweight waterproof ski pants are built for long-term use and everyday reliability.

Sustainability is integrated through responsible material choices, including PFAS-free DWR treatment and a repair kit for extended product life. The Y-3 shell pants reflect The Mountain Studio’s commitment to swiss alpine engineering, durability, and timeless style. From groomers to backcountry, these premium ski trousers deliver exceptional quality and performance for every winter scenario.

Alp-3 is The Mountain Studio’s proprietary membrane technology. It's a hydrophilic membrane that delivers an excellent 30,000 mm water column and 30,000 g/m2/24 hrs breathability. This supple 3-layer stretch fabric is made from nylon and spandex, and has been given a PFAS-free DWR treatment on the outside.
