A adidas by Stella McCartney running cap.

This adidas by Stella McCartney cap keeps your eyes shaded when you're out for a run on a sunny day. An adjustable strap in back ensures an ideal fit, and creates a space to comfortably pull your ponytail or bun through. The six-panel construction gives it a classic shape, done in a bold pop of colour that tops off any outfit — workout or otherwise — with a statement.
