As tennis fever strikes in time for the US Open, Irvine, CA-based Croota Underwear (www.croota.com) is getting the American male ready on National Underwear Day for one of the highly anticipated sporting tournaments of the year by highlighting one of its newest ranges, “Tennis Fever.”

Inspired by the Croota in-house design team’s love for tennis, the lo-rise hipster trunk comes in two versatile color variations, Sky Blue and Blue Indigo, and also features three different embroidery colors on the lower back. The numbers “00” are in a bold-faced white font on the top right of the rear to symbolize the starting score of a tennis match. It’s the perfect brief for guys on or off the court.

“Tennis Fever” is made of 95% cotton and 5% spandex, and retails for $18.90 USD.
