The Rab Kinetic Alpine Stretch Ski Jacket combines the proven performance of Rab's Proflex stretch fabric technology with a ski-specific cut and feature set — delivering a hardshell jacket that moves with you rather than against you. Based on Rab's acclaimed Kinetic Alpine range, this ski-optimised version provides the supple, softshell-like feel and outstanding breathability that defines Proflex, all within a fully waterproof construction that handles whatever the mountain throws at it. Proflex is a uniquely stretchy, breathable waterproof fabric that has made the Kinetic range one of the most respected hardshell lines in the UK outdoor industry. Unlike conventional stiff hardshells, the Kinetic Alpine Stretch moves naturally with dynamic skiing movements — making it equally effective for aggressive all-mountain riding and long ski-mountaineering days. A helmet-compatible hood, pit zip venting, and ski pass pocket complete the package.
