“Both parents and kids are loving the styles and fashions we’re making available. We get great e-mails from happy parents, and as a father of three, that really means a lot.”

Call it the softer side of Dan Caldwell, co-founder of the mixed martial arts pop culture phenomenon TapouT.

TapouT clothing and gear are one of the more stunning retail success stories in recent years. It started with an annual gross of $30,000 in 1999, and earnings approached $200 million by 2009.

But lest you think Caldwell is strictly interested in the ferocious fashion aspects of mixed martial arts, guess again. After all, his kids (ages 4, 7 and 11) also need clothes, and when Caldwell realized how much time it was taking to run from retail outlet to retail outlet in search of the coolest duds, he decided to take matters into his own hands.
