An official uniform of sport, the unofficial uniform of the streets. In the blink of an eye, the track suit spread from the courts and spilled out to every little corner of the world. Exact location? Unimportant. Decade? Hard to say. Because it has proved to be timeless, and this adidas track jacket shows why. A clean, simple sport style that's never out of place. Plus, it was made with recycled materials, part of adidas' ongoing efforts to help create a sustainable future. 100% Recycled polyester.
