Kappa is a sports and leisure clothing company established in Turin, Italy in 1916. It is one of the famous sportswear brands. Since its inception, the brand has provided sponsorship to various sports teams. Its main products are designed for the sporting goods market. Teams such as South Africa and Jamaica are loyal supporters of Kappa.

In 1969, a pair of male and female models sat down to rest while shooting a sportswear advertisement for Kappa. The photographer accidentally captured this scene, and this world-famous brand LOGO was born. This romantic character mark is still used today and has become a visual symbol that is popular around the world. Kappa is the 10th letter of the Greek alphabet. Kappa's LOGO is pronounced Omini (Gemini). The reason why this pair of men and women sit back to back is because Kappa believes that men and women can share the joy of sports together. And men and women should also support each other to achieve their goals, both on and off the field. Because Kappa's trademark is a man and a woman sitting back-to-back, people are used to calling Kappa back-to-back.
