This adidas by Stella McCartney cap is built to keep up with your workout, then fold away neatly when you're done. If you want, that is, because its clean, fashionable silhouette is also designed to be styled beyond your run. Lightweight and packable, it shields your eyes from the sun so you can push forward with confidence and focus. An adjustable bungee in back lets you fine-tune the fit on the move. This product is made with at least 50% 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.
