W 2L Stretch Insulated Jacket
Black Onyx

The S-5 W insulated jacket from The Mountain Studio is engineered for women who ski and ride in cold, demanding winter conditions. This mountain ski jacket uses a 3-layer ALP-3 stretch membrane for waterproof protection and breathability, paired with PrimaLoft Gold Eco synthetic insulation. The body features 60g insulation for warmth, while the sleeves use a lighter 40g fill for mobility and comfort. The adjustable, helmet-compatible hood and snow skirt provide reliable coverage against wind and snow during active mountain use.

Performance details include fully taped seams, a watertight 2-way front zipper, and underarm ventilation zippers for rapid airflow adjustment. The jacket features a ski pass pocket on the sleeve, one chest pocket, two hand pockets, and two inside chest pockets for secure storage. High-reach arm construction and 4-way stretch fabric ensure freedom of movement, while the integrated chin guard and detachable vertical brand logo add functional refinement.

The S-5 W is available in beige, black, green, red, and white, supporting a range of styling options. Signature side cut, Cohaesive cord stoppers, and Aqua guard technology contribute to a clean silhouette and minimalist design. This insulated ski jacket transitions easily from groomed runs to deep powder, and suits city use or outdoor activities in cold weather.

Sustainability is addressed with PrimaLoft Gold Eco insulation made from 55% recycled content and PFAS-free ALP-3 membrane technology. The Mountain Studio applies swiss alpine engineering and responsible material choices to every piece, ensuring the S-5 W jacket remains durable and reliable season after season. Built for long-term use and everyday mountain performance.
