Super-light insulating jacket for winter activities The Rime Light Flex is a particularly lightweight warm jacket with synthetic insulation that is versatile. Thanks to the stretch insulation and side inserts made from elasticated Polartec® Power Grid™ fleece, it fits close to the body on ski tours, hiking, mountaineering and skiing, allowing you to combine it with other items of clothing according to the layering principle. The Pertex® Quantum Air lining makes the jacket wind-repellent and at the same time particularly breathable, extremely light and compressible. If you don't need the jacket, simply pack it into the bag provided - the Rime Light Flex can go anywhere.
