Wind and weather protection with minimal packing volume, highly elastic and very light. The innovative X-BIONIC® RainSphere Shirt combines the advantages of a very elastic high-tech shirt with the ones of an ultra-light rain jacket, thanks to the innovative X-BIONIC® technologies. The patented 3D Bionic Sphere® System is integrated in the hybrid of a shirt and a rain jacket. It ensures efficient sweat management, leaving a cooling moisture film on the skin. A special membrane composes the shirt’s functional outer layer. It is water-repellent and flexible without flapping in the wind and very light with a minimal packing volume.
