Insulated jacket in a stretch fabric for resort skiing and snowboarding. The S-1 is the ideal solution for active skiers who prefer an insulated ski jacket but still demand premium performance.

The jacket features The Mountain Studio’s proprietary ALP-3 membrane technology, paired with a 60g lightweight PrimaLoft synthetic insulation layer in the body and a slightly thinner 40g layer in the arms. All this makes the jacket fully waterproof and windproof while being breathable. The outer stretch fabric and high-reach arm construction make the jacket both stretchy and comfortable, providing full mobility support. The jacket also features a ski pass pocket, a snow skirt and a large helmet-compatible hood.

The S-1 is the perfect choice for the resort-based skier who wants some extra warmth on cold days. The jacket is light, flexible, and just warm enough to take the edge off on cold mid-winter days at high altitude.
