Keep your workout essentials together in style with adidas by Stella McCartney's roomy gym bag. Classic in black, it features a combination of mesh and faux leather panels, leaving a sporty imprint. The sides are trimmed with a zip-around feature, which can be undone to make the style even roomier, and the design is completed with two zipped pockets for your valuables – one on the exterior, and another inside. Carry yours by the handles or wear it across your body with the detachable shoulder strap.
