Some days call for sporty style that keeps up with life's pace. This adidas by Stella McCartney tee delivers with its casual cut and breathable cotton fabric. Elastic on the back contours the silhouette, and a distinctly curved hem makes movement feel free. Inspired by workout wear from the '70s and '80s, it blends the best of comfort and style. This product has been made with at least 70% renewable materials. Switching to renewable material sources offers more options to reduce our reliance on finite resources. We choose renewable materials because they are natural resources that can be planted and grown again. This is unlike fossil fuel based materials, which once used, we cannot replenish. Renewable materials are not only natural materials, but also bio-synthetic materials that have a plant feedstock instead of fossil fuel. This feedstock is chemically processed into intermediate substances and is turned into synthetic materials in the end. By purchasing this product you are supporting regenerative organic cotton agriculture.
