It means that these leggings are a perfect statement well beyond gym walls. A hidden back pocket lets you store your key. This product is made with at least 70% recycled materials. By reusing materials that have already been created, we help to reduce waste and our reliance on finite resources and reduce the footprint of the products we make.
