Nike Basketball Introduces Caitlin Clark as a Signature Athlete and Unveils Her New Signature Logo “Nike’s signature roster features all-time greats, and I am incredibly proud to join some of the best athletes in the world,” says Caitlin. Caitlin and Nike are unveiling her new signature logo: an instantly recognizable combination of interlocking Cs — tucked between the larger letters is a smaller, hidden C that represents how Caitlin’s game was built from the inside out. The logo will come to life for the first time with her logo collection launching on October 1 on nike.com. #madeforthew #nikebasketball #caitlinclark
