Chase your runner's high in style with the Stella McCartney TruePace Metallic Running Jacket. The mood-enhancing metallic fabric will have you feeling like the human embodiment of a disco ball, while the various high-performance features will keep you running outdoors comfortably at all times. Crafted from 100% recycled polyester, the jacket is lined with mesh to keep air flowing when you need it most, with an open slit at the back for added breathability. A bungee-adjustable hood comes in handy for those drizzly, wind-swept days. And, when the sun comes out, the jacket can be easily folded and stored into its own compact pocket—a bonus for day trips and temperamental weather, alike. Easily incorporate the lightweight jacket into your everyday wardrobe, thanks to its chic oversized silhouette and shiny finish.
