This ultra-light jacket will keep me warm and dry, while being active. It protects me from mild rain, snow, and wind while maintaining my micro-climate. I name it OptimumPerformance. The high level of breathability is essential to keep my body dry, the windproof and water repellent properties keep me protected. DWR treatment makes the water drops slide off the surface. Additional reflective accessories on the back will make me more visible and safe at night - NightVision. The PrimaLoft layer on back and front keeps my body warm. For trail running, trekking, and cross-country skiing in spring autumn and winter.
