The On Lumos Weather Jacket has everything you need to train all winter long. This ultralight jacket protects against wind and light rain thanks to its PFC-free DWR treatment. The high-quality Japanese fabrics are windproof and keep your body temperature regulated, even when you are resting. Plus, it has a cap-design hood that will keep the rain out of your face and stays in place, even when you are running into a headwind. Go ahead and run in the rain or run in the dark. As part of On’s Lumos collection, this jacket features highly reflective detailing that helps keep you visible when the light fades. A micro-ventilation pattern in the design allows for 360 degrees of ventilation, keeping you comfortable for longer. Plus, the jacket packs down into its own chest pocket, so it's perfect for throwing in your bag when you are traveling or running trails. Day or night, sunshine or rain, you will be ready for anything in the stylish On Lumos Weather Jacket. Read more in our On Lumos Weather Jacket review.
