The On Men's Weather Jacket is the ultimate running jacket made especially for ultralight protection whatever the weather. Thanks to its lightweight Japanese fabrics, the Weather Jacket offers 360° ventilation in an ultralight package that's also tear proof and fast drying. The highly stretchable polyester and elastane fabric features a micro-ventilation-pattern for high breathability and the four-way-stretch polyamide on the back adds protection. Additionally, the advanced DWR (durable water repellent) coating ensures rain rolls off, ensuring you stay warm and dry for all day comfort. Enjoy the cap-design of the jacket's hood, which keeps it in place in the wet, water-resistant zippered pockets provide protection for your valuables and the entire jacket folds quickly into its own breast pocket, allowing for ultra-small storage and portability. Every element of the On Men's Weather Jacket is made with the practicalities of running in the elements in mind.
