British designer Stella McCartney stays true to her high-eco ethos within her capsule collection for Adidas, offering up design-led performancewear with a reduced carbon footprint. Created with a yarn crafted in collaboration with Parley for the Oceans, sourced from waste, this breathable stretch fabric sculpts a figure-fitting round neck tee with short sleeves, a straight hem, mesh panelling and a printed logo to the rear.
