Used sparingly last winter Brooks Shield Hybrid Jacket 2.0, now too small. Great warm jacket with lots of storage. She has rubbing marks on the back from my packs. Semi fitted fit, pit to pit appx 18/18.5 inches From Brooks site: “Our cold-weather, insulated running jacket is super-protective. Stay warm, dry, and well-equipped for your run thanks to the weather-resistance and convenient pockets.”
