3L Rugged Ripstop Insulated Jacket
Castle Wall

The S-9 is built for skiers who want the protection and mobility of a technical 3-layer shell, with just enough insulation to take the edge off the cold. Lightweight, soft, and highly comfortable, it is designed for active resort skiing and snowboarding where freedom of movement matters just as much as weather protection.

The ALP-3 mini-ripstop shell is waterproof, windproof, and breathable with a 20,000/20,000 rating and fully taped seams, while PrimaLoft Stretch insulation (40g body, 20g sleeves) adds targeted warmth without compromising flexibility. Two pleated front pockets with flaps, underarm ventilation zippers, a helmet-compatible hood, 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. Built with a rugged 88% nylon ripstop shell, a PFAS-free DWR treatment, and PrimaLoft Stretch insulation, it balances comfort and protection from the first run of the day to the last. A repair kit is included.

Available in Castle Wall, the S-9 is made for active resort skiing and snowboarding. This insulated ski jacket is trusted for targeted warmth, dependable protection, and a lighter, more mobile feel.
