The On Women's Weather Lumos Jacket is an ultralight jacket that protects you against wind and light rain. Part of the Lumos Collection, this jacket features highly reflective detailing that helps keep you visible when the light fades. Thanks to a PFC-free DWR treatment, it offers protection against light rain. The high-quality Japanese fabrics are also windproof, keeping your body temperature regulated, even when you rest and the cap-design hood is ideal for keeping you comfortable and hyper-focused. This entire jacket packs down into its own chest pocket. A micro-ventilation pattern in the design also allows for 360° ventilation, keeping you more comfortable for longer. Whatever length or style of the run, you can get out there with the On Women's Weather Lumos Jacket.
