adidas Originals celebrate the Three Stripes heritage in tennis with a collection by Pharrell Williams. Aptly arriving in time for the U.S. open, the chic on court style extends to this belt pack – a sleek and elegant design that’s ready for game, set, match. The main compartment zips open to reveal ample storage space for all the smaller essentials, and even maybe a spare tennis ball or two. Paying homage to vintage tennis bags, the zips and bottom studs throwback to the golden era in the sport.
