Built for demanding ascents and descents on big mountains, the Sogn shell jacket has our strong 3-layer HELLY TECH Professional membrane and a DWR treatment. You'll stay dry while digging deep into powder. The Sogn Shell 2.0 Jacket is based on a former best-selling style of the same name. We upgraded it with key input from our ski professional ambassadors, to help you go further this season. Ski details include the RECCO Advanced Rescue system, a ski pass pocket, a helmet-compatible hood, powder skirt and fusion modular jacket-to-pant system.
