Our flex1 fabrics are the ultimate choice for high-intensity mountain activities. We use this proprietary single-ply fabric because it strikes the perfect balance between protection and performance.

Whether you are trekking, climbing, or ski touring, flex1 provides the windproofness and durability you need without sacrificing breathability. Its inherent stretch allows for a full range of motion, while its moisture-wicking properties ensure you stay dry and comfortable when the intensity ramps up.
