Zone3 is known for its high-performance wetsuits and triathlon / open-water swimming gear. It was founded by elitetriathlete James Lock, who started the company after competing internationally and identifying opportunities to improve swim specific wetsuit design.
Early focus was on creating wetsuits that offered real performance advantages—such as easier removal and better efficiency in the water—leading to the launch of the originalAspire wetsuit, which quickly gained acclaim among competitive swimmers and triathletes. Over time, Zone3 expanded its product range to include advanced wetsuits like the Vanquish
and Vision series, as well as swimwear, triathlon apparel, goggles and accessories designed to support athletes from beginners to elites.
Driven by athlete-led design and rigorous testing, Zone3 has grown into a globally recognised brand with products sold in dozens of countries worldwide. Along the way it has earned industry recognition, including the Queen’s (now King’s) Award for Enterprise for innovation and international trade, reflecting its commitment to performance, quality and continuous improvement.
Today Zone3 remains focused on helping swimmers and triathletes perform better in the water, blending cutting-edge materials and thoughtful design to reduce drag, enhance comfort and support speed and efficiency across open-water and race environments.
