The splashy neon logos and beachy vibe of brands Billabong and Quiksilver ruled the U.S. fashion scene in the 1990s and early 2000s, when teens across the country wanted to channel surfer culture. In time, the boom subsided, and American teens moved on to the next big trend. Now with the acquisition of Australia’s Billabong International, Huntington Beach surfwear and active apparel company Boardriders — owner of the Quiksilver brand, which has fewer stores than in its heyday — is looking to tap global interest in the action-sports lifestyle.
