This extremely light Alpine Wind Jacket offers protection for ambitious trail runners. The Dynashell Ultralight fabric is wind- and water-resistant, breathable and feels pleasantly soft against your skin. Thumb loops ensure your sleeves stay put and lend wind protection fo your hands and wrists. The back of the jacket is made in part out of mesh fabric to increase breathability and ventilation, which in particular makes carrying a pack more comfortable. A snugly fitting hood can be rolled up and clipped in firmly when needed so it does not annoyingly bounce around when running. If you don’t need the jacket anymore, you can pack it into its own integrated stuff sack in the hood. Its minimal packsize means the jacket can find room in even the smallest places so you always have it at hand when needed.
