(CNN) -- You could say that a simple pair of running shorts was the trigger that launched a multimillion-dollar business and radically shifted the lives of basketball coaches Susan Walvius and Michelle Marciniak. In August 2007, Walvius, who was then the head women's basketball coach at the University of South Carolina, and her assistant, Marciniak, had just finished a long day teaching at a summer basketball camp. They sat exhausted in the gym, looking forward to a good night's rest. Then Walvius -- thinking about her comfy running shorts -- experienced what she describes as an "aha moment." "I looked at Michelle and said, 'I love this fabric, and I'd love to have bedsheets from this stuff.' Michelle said, 'Let's do it.' " And with zero formal business experience, the two women stepped boldly into the world of entrepreneurship.
