Gore-Tex Pro 3L Shell Vectran Pant Man

The Mountain Studio Y-7 PRO GORE-TEX® Pro 3L Shell Vectran Bib Pants

Engineered in Switzerland and developed in close collaboration with professional Alpine guides and ski ambassadors, the Y-7 PRO Bib Pant is an ultra-rugged, 3-layer GORE-TEX® Pro shell built for severe off-piste and backcountry skiing. Designed to endure the harshest alpine weather, it delivers ultimate stormproof protection combined with high-tenacity reinforcement for maximum longevity in extreme terrain.

GORE-TEX® Pro 3L, Vectran® Armor & Sorona® Insulation Constructed from heavy-duty 150-denier recycled polyamide with a 3-layer GORE-TEX® Pro ePE membrane, the Y-7 PRO delivers an impressive 30,000 mm waterproof and 30,000 g/m²/24h breathability rating. To withstand sharp ski edges and rough rock surfaces, it features ultra-durable Vectran® fiber paneling across the knees and inner lower legs—a material five times stronger than steel by weight. A tall integrated bib section with adjustable suspenders keeps deep powder out, while an ergonomic Dupont Sorona® insulated lumbar insert guards the lower back against cold drafts. Complete with YKK® AquaGuard® waterproof zippers, thigh ventilation zips, adjustable waist tabs, elastic snow gaiters, and an included repair kit, it offers an uncompromised alpine armor in an earthy Otter tone.
