This lightweight softshell jacket is my perfect choice for running and outdoor fitness. It performs excellently at trail running and trekking. Its perfect breathability gives me a feeling of freshness while active. Freedom of movement is achieved by its 4-way-stretch material that is supplemented by elastic stretch fabric inserts on sleeves, back and waist - up to the detail ergonomic construction. Reflective prints are placed on the back for better NightVision. The material itself is 100% waterproof. As it is ultrasoft and light the seams can not be taped - cause of that the jacket is characterized as water repellent. Water repellency, windproofness, and high breathability make it perfect for chilly weather and light rain.
