The Z-4 shell jacket from The Mountain Studio is designed for active skiing and snowboarding in resort and backcountry terrain.

This mountain ski jacket uses a soft, durable 3-layer ALP-3 mini ripstop fabric that is waterproof, windproof, and highly breathable.

Seam-free shoulders and high-reach arm construction deliver unrestricted movement, while the ergonomic fit ensures comfort during long days in harsh weather.

Technical features support reliable performance in changing conditions.

The helmet-compatible hood, internal snow skirt, and ski pass pocket offer practical functionality for mountain use.

Underarm ventilation zippers provide responsive airflow control, and fully taped seams with YKK Aquaguard zippers enhance weatherproof protection.

The jacket includes two chest pockets, two hand pockets, and an inside chest pocket for secure storage.

Minimalist design and refined detailing create a clean silhouette.

The stretch fabric and signature sidecut hem and cuffs contribute to a tailored fit and modern look.

This ski shell jacket transitions easily from groomed runs to powder, and suits city use or outdoor activities beyond the slopes.

Sustainability is addressed through PFAS-free DWR treatment and a repair kit included for long-term wear.

The Mountain Studio focuses on responsible material choices and Swiss alpine engineering, ensuring the Z-4 shell jacket remains reliable season after season.

Built for men and women, this three-layer technical shell jacket balances comfort, durability, and timeless style.
