The United States Tennis Associates sells official U.S. Open tennis apparel through its online shop, USTAShop.com. In addition to apparel, USTAShop.com is also a great source for official rule and etiquette books.
You can use the website's search bar to find relevant products by entering in "U.S. Open apparel." Click on the dropdown category menus to filter your results by price or type of item. Results can be viewed in a list or grid, and you can sort results by popularity or price (ascending or descending).
The USTA partners with designers and other brands, such as Ralph Lauren and Wilson Sporting Goods, to craft and sell official gear. The USTA website offers official goods from affiliated designers directly, although you can also go directly to the respective manufacturer's websites.
Official Ralph Lauren U.S. Open gear is available at RalphLauren.com. You can search by category, such as men, women, children, baby, home and more, and sort results by bestsellers, relevance, newest arrivals or price. Finding specific USTA items, however, can be more difficult than searching directly on USTAShop.com
Similarly, visit Wilson.com to find official USTA sporting goods made by the company. Unlike on RalphLauren.com, you can easily identify official U.S. Open tennis equipment, including tennis balls, rackets, bags and more, simply by entering "U.S. open" in the search bar on the website's homepage.
Most other partners of the USTA and U.S. Open offer the same signature apparel and other goods on their respective sites.
