TrueStrength training leggings from adidas by Stella McCartney featuring black, citron yellow, recycled polyester blend, logo print to the side, colour-block panelled design and elasticated waistband. POSITIVELY CONSCIOUS: This Planet Conscious product is crafted from certified recycled or upcycled materials, which helps you make a better choice for the environment as they generate less energy, save water and reduce the need for new raw materials. For recycled synthetic clothing products we highly recommend using a microfibre-catching washing bag to ensure that no microplastics that can pollute water are released in the process..
