O'Neill is a pioneering surfwear and wetsuit brand that was founded in 1952 by Jack O’Neill in San Francisco, California. Initially operating out of a humble surf shop, Jack O’Neill is widely credited with inventing the neoprene wetsuit, a groundbreaking innovation that allowed surfers to stay warm in cold waters and thus extend their time in the ocean. This invention not only revolutionized cold-water surfing but also helped grow the global surf culture. Over the decades, O'Neill evolved from a niche brand into a globally recognized name in surf and lifestyle apparel, offering a wide range of products including boardshorts, wetsuits, casual wear, and accessories. The company has remained true to its roots, focusing on ocean-inspired design and sustainable innovation, with environmental initiatives such as the O’Neill Blue program, which supports ocean conservation efforts. Though now owned by a Dutch company, O'Neill maintains its original spirit—blending surf heritage with modern performance and style.
