Tennis has been known for some offbeat sponsorships—it’s never been all “Nike or Adidas.”

There’s always been a strong foothold for smaller, more fashion-forward labels: Sergio Tacchini, Fila, Lacoste and now, Uniqlo. News of Novak Djokovic’s split with Tacchini (he actually ditched Adidas to sign with McEnroe’s old sponsor) and signing with Uniqlo shocked the tennis world a few months back. The move sounded a bit questionable at first, but anyone familiar with Uniqlo’s HeatTech thermal wear knows that they’ve been dabbling in high-tech fabrics for a while. The tennis gear, timed with the US Open, is finally hitting stores, and we’re most interested in the zipper-placket polo in tennis white. It’s decidedly sporty, but should come in handy the next time you’re slated for a round of mixed doubles.

You’re always up for a round of mixed doubles.
