ZONE3

Warm water, less kit.

Summer is the easiest time of the year to swim outdoors.

Our swimwear is made for it. Chlorine proof, sunscreen resistant, UPF50+: Swimwear built to survive a whole summer of swimming, and more.

Katrine Græsbøll Christensen has raced 13 long-distance triathlons.

She has been on 5 podiums in 6 races in the 2026 season so far. And she lines up at IM Kalmar this weekend.

Ask her what race week actually looks like, and the answer isn't a mindset trick. The answer is a race day routine - a sequence, repeated and refined until it needs no thought at all.

Learn how the Pros prepare for race day.

The aero setup, complete.

Aeroforce-X II Trisuit, Speedbelt and Calf Sleeves, each developed with Nopinz. One system from swim exit to finish line.

This is the kit for triathletes who think in watts and seconds.

Swim, bike, run, and the minutes in between. Transitions are the only place on a race course where time is saved without fitness.

Get tips on how to set up your triathlon transition area, the kit that makes both faster & the mistakes to avoid. From wetsuit removal to aero race belts.

Polarised goggle lenses are made for summer.

They minimise reflected glare off the surface in bright, sunny conditions, exactly what you need when swimming open water.

Comment 'GOGGLE' for the guide to find your perfect pair.

Bantham done ✅
Our team was on-site in Devon all of last weekend for Level Water's Swoosh & Boomerang, meeting swimmers and helping them find their perfect wetsuit and swim goggles!

Level Water exists to close the biggest unmet need in sport: swimming access for children with disabilities. Every entry at Bantham and all of their other open water swim events go towards real one-to-one lessons.

Zone3's support doesn't stop when the tents come down. £1 from every goggle sold goes to Level Water year-round, funding an extra 18 lessons a week and opening up pools that were previously out of reach.

Well swum, everyone. Kudos

London, this weekend belongs to triathlon. We'll be at the T100 London expo at ExCeL helping you find the right goggle fit and lens choice plus the right wetsuit or swimskin for the conditions.

Same weekend, same venue: the World Triathlon Championship Series returns to London for the first time since 2015, with over 100 of the world's best racing for Olympic qualification points on the road to LA 2028. We're looking forward to cheering on our Zone3 athletes as they take to the course.

Are you racing T100 this weekend?

Built for swimming. Ready for everything else on the water.

The Active-Flex is Zone3’s most versatile wetsuit. Smoothskin and nylon-lined neoprene make it durable enough for paddleboarding and kayaking, while a lower buoyancy rating keeps your legs low in the water, exactly where breaststroke needs them.

A Yulex natural rubber chest panel adds warmth with a lighter footprint than standard neoprene.

Perfect for every activity this summer.

Zone3 athletes took to the swim, bike and run this weekend across three continents’ worth of racing, and the results speak for themselves.

From Ironman 70.3 podiums to a Para Series world title and a mixed relay medal on the world stage, the Athletes backed up the training with performance where it counts: on race day.

🥇 Henry Urand: 1st (PTS3), World Triathlon Para Series Hamburg
🥈 Kieran Lindars: 2nd, Ironman 70.3 Swansea
🥉 Jess Fullagar: 3rd, Mixed Relay, WTCS Hamburg
4️⃣ Rebecca Anderbury: 4th, Ironman 70.3 Swansea
5️⃣ Laura Addie: 5th, Ironman 70.3 Vitoria-Gasteiz

Six athletes, five races, one standard: tested, trusted, performance-led. Every result built on the same discipline that shapes our gear.

Athlete approved. Performance proven.
