This black Run top is a fine example of how Adidas's technical knowledge is seamlessly merged with Stella McCartney's contemporary aesthetic. It's cut from signature Climalite® jersey to a traditional crew-neck silhouette that's subverted with an adjustable bungee-drawcord waistband at the back and tonal mesh panels. Wear it to the gym with a pair of the label's leggings and black trainers.
