Zone 3 Wetsuits

Zone3 has grown from a small university project into one of the world’s leading triathlon and open‑water swimming brands. Founded by elite triathlete James Lock at Loughborough University, the company began with a simple goal: to create faster, better‑performing wetsuits that could give athletes a real competitive edge. What started as Lock designing suits for his own races quickly evolved into a brand trusted by beginners, age‑groupers, and professionals worldwide.

Since the first official Zone3 wetsuit launch in 2009, the collection has expanded dramatically. Today, Zone3 offers a complete range of triathlon wetsuits, SwimRun suits, and open‑water essentials designed to support every stage of an athlete’s journey — from first‑time swimmers to podium‑chasing competitors.

At ProSwimwear, you’ll find one of the UK’s widest selections of Zone3 wetsuits in stock. Our range includes everything from entry‑level options for new triathletes to high‑performance models like the award‑winning Zone3 Vanquish, engineered for maximum flexibility, buoyancy, and speed.

We also carry a full line of Zone3 triathlon accessories, including timing chip straps, neoprene caps, gloves, and buoyancy aids — perfect for colder water or long‑distance training. Zone3’s innovation doesn’t stop at wetsuits either; their SwimRun suits and durable training swimwear are designed to pair seamlessly with Zone3 goggles, caps, and training equipment.

Whether you’re preparing for your first triathlon or upgrading your race‑day kit, Zone3 delivers performance‑driven design trusted by athletes around the world.
