W 3L Rugged Ripstop Insulated Down Jacket
Castle Wall

The S-11 W is a down-insulated ski jacket built for skiers and snowboarders who want the protection and mobility of a technical 3-layer shell, with added warmth for colder days on the mountain. Lightweight, protective, and highly comfortable, it is designed for active resort skiing where freedom of movement matters just as much as weather protection. The result is a jacket that feels substantial enough for deep winter, while still maintaining the lighter, more mobile character of a modern technical ski piece.

The rugged ALP-3 ripstop shell is waterproof, windproof, and breathable, while the 700 fill power RDS-certified down adds reliable insulation without turning the jacket overly bulky. Two pleated front pockets with flaps bring both function and character, while a helmet-compatible hood, underarm ventilation, and a snow skirt round out a design made for long days on snow and changing mountain weather.

Minimalist design and refined lines reflect The Mountain Studio's commitment to Swiss alpine engineering and timeless style. Fully taped seams, SAB zippers, and a PFAS-free DWR treatment support dependable, long-term performance on cold midwinter days on piste and around the resort.

Available in Castle Wall, the S-11 W is warm, protective, and built to move — a strong choice for cold days on the mountain and beyond.
