PUS Polo Assn. is an official brand of the U.S. Polo Association (USPA), a nonprofit polo sports organization in the United States founded in 1890, making it one of the oldest sports management organizations in the world. The recognized brand offers men's, women's, and children's clothing, as well as shoes, handbags, travel items, and accessories in 180 countries worldwide. It symbolizes the aesthetics of the upper class of the former American elite, and wearing its clothing and accessories conveys a sense of exclusivity and elitism. It is primarily a combination of elite sports chic, classics with elegance, and functionality. These features have been incorporated into mobile device accessories to create unique collections of bright, trendy, and sport-inspired phone cases. The case from the Gradient collection features a polycarbonate plate with a subtle blue gradient effect. The slim silhouette does not overwhelm the smartphone, and the flexible frame that securely encases the device provides protection and a sleek, elegant appearance. License.
