Pushing the limits of wetsuit innovation since 1952

AREA 52: O’Neill’s exclusive R&D facility, staffed by full time engineering, design and prototyping teams who work closely with The World’s Best Athletes to push the limits of wetsuit technology.

AREA 52 allows us to hand-build and refine multiple rounds of prototypes in the same fashion that Jack himself pioneered over sixty years ago. Extensive prototyping, fit checks and testing in the frigid waters of Northern California provides unparalleled insight when creating the best fitting, most functional wetsuits on the planet. O’Neill Wetsuits is still located in Santa Cruz, California, the birthplace of modern cold water surfing and the proving ground for materials, features and benefits that keep you in the water longer. Over 60 years and countless industry firsts later, O’Neill’s commitment to leading innovation continues stronger than ever.

SINCE THE BEGINNING.
