Part of a covetable capsule with adidas, Stella McCartney embraces sports-luxe with this high-fashion take on a classic track jacket. Crafted from black jersey, the style is adorned with the signature 3-stripe sleeves, a baseball collar, ribbed cuffs and hem, and a logo detail at the chest. But our favorite element is the delicate lace insets along the front and arms – a boudoir-chic touch to an athletic style.
