It took almost a full decade for Guardian Sports to become financially self-sustaining, and even longer to finish paying back The Hanson Group for the seven-figure costs of external lab testing and an early bulk purchase of more than 100,000 caps—that happened just last year. But the bustling scene suggests that business is good today. In the warehouse, towering stacks of Guardian Caps inventory have overtaken what was once an employee exercise area, like cubed cardboard weeds. In the loading dock, a truck drops off a fresh supply of green and maroon caps air-shipped from the company’s factory in Dongguan, China after their stockpile of those colors ran out.
