Vanquish-X Wetsuit

The Vanquish-X represents the pinnacle of ZONE3 wetsuit innovation, developed for athletes who demand more from every stroke. Meticulously researched, tested, and refined, it is engineered to improve swim efficiency, reduce physiological cost, and help triathletes exit the water with more energy for the race ahead.

Its performance is backed by independent testing at Loughborough Sport, where the Vanquish-X delivered measurable improvements across every key metric. Averaged across three athletes, results showed a 10.3% improvement in efficiency, a 5.2% increase in speed over 750m, and a 25% reduction in physiological load measured by blood lactate. These results reinforce the suit’s core purpose: to help athletes move through the water faster, more efficiently, and with less energy loss.

Combining exceptional flexibility, maximum buoyancy, advanced warmth technologies, and a refined fit, the Vanquish-X is designed to support a stronger body position, a freer stroke, and a more controlled swim from start to finish. Every element has been developed with one goal in mind; to deliver the kind of marginal gains that make a meaningful difference on race day.

BIO-RUBBER TECHNOLOGY

Exclusive Yamamoto Bio-Rubber on the thighs is designed to increase blood flow, reduce fatigue build-up in the legs, and help you exit the water with more power available for the bike.

X-10 EXTREME SHOULDER PANEL

Built with premium #40 SCS 1mm SCS Nano neoprene, this shoulder construction delivers exceptional flexibility for a freer, less restrictive stroke and greater efficiency over distance.

MAXIMUM BUOYANCY CONSTRUCTION

Aerodome and NBR buoyancy panels work together to lift the body into a higher, more streamlined position, helping to reduce drag, improve efficiency, and conserve energy.

ALPHA TITANIUM LINING

This advanced upper-body lining helps improve warmth and circulation, supporting comfort and race-day freshness without negatively affecting buoyancy, flexibility, or comfort.

Key Features

Exclusive Yamamoto Bio-Rubber Technology. Developed under a global exclusive agreement with Yamamoto Corporation, Bio-Rubber uses infrared-emitting technology designed to increase blood flow, reduce lactic acid and fatigue build-up in the legs, and help athletes start the bike with more power in reserve.
Alpha Titanium Upper Body Lining. A unique five-layer construction featuring Titanium Alloy is designed to improve warmth and circulation across the upper body, helping athletes retain heat and stay fresher through the swim without compromising buoyancy, flexibility, or comfort.
Silk-X Inner Lining. Premium Silk-X lining creates a smoother feel against the skin and helps the suit come off more cleanly in transition.
X-10 Extreme Shoulder Panel. Engineered with #40 SCS 1mm SCS Nano neoprene, this advanced shoulder panel construction delivers exceptional flexibility and freedom of movement for a lighter, more efficient stroke.
B.R.E Body Rotation Enhancement. Strategically positioned chest panel technology is designed to improve body rotation and increase distance per stroke, helping swimmers move through the water more efficiently.
Maximum Buoyancy Construction. Aerodome and NBR buoyancy panels help raise the body into a stronger, more streamlined position in the water, reducing drag and preserving energy over the course of the swim.
BRS Mark 0.3mm SCS Sleeves. Ultra-light sleeve construction supports natural arm rotation and a more unrestricted feel through every phase of the stroke.
Cool-Spot Forearm Panels. Designed to enhance feel for the water and improve the catch phase, helping swimmers maintain a more connected and controlled stroke.
Updated Collar and Leg Design. Refined construction improves overall fit, comfort, and security, helping the suit feel more natural and race-ready from start to finish.
Engineered for Race-Day Freshness. Every element of the Vanquish-X is developed to improve efficiency, reduce wasted energy, and help triathletes exit the water fresher for the bike and run ahead.

TEST RESULTS FOR THE Vanquish-X Wetsuit

Elite speed. Proven efficiency.

The Vanquish-X was the highest-performing suit in the independent Loughborough Sport study of three athletes. It delivered measurable improvements in every key metric — speed, efficiency, and physiological load — confirming its elite-level performance advantage.

Key Findings (Averaged Across 3 Athletes)

+5.2 % faster over 750 m

+10.3 % improvement in efficiency

–25 % reduction in physiological load (blood lactate)

Interpretation:

Averaged results across three athletes showed the Vanquish-X delivered the greatest gains in both performance and efficiency, with the lowest physiological cost recorded. These findings reinforce its design intent: to deliver measurable, real-world marginal gains for experienced athletes.

The fastest suit tested — proven in an independent Loughborough Sport study of three athletes.

FIT GUIDANCE

Getting the right fit

Snug everywhere, restrictive nowhere. You should feel the suit holding your body without pinching at the shoulders or compressing your chest to the point where breathing feels laboured. If you can't take a full breath on land, size up. If there's loose material across the shoulders or chest, size down. Air pockets at the lower back usually mean you need a longer suit, such as an MT (Medium Tall), not a smaller size.

If you're between sizes

Size down if you're racing — a tighter fit gives you more from the suit's buoyancy and reduces water flushing. Size up if you're prioritising comfort for longer open water swims or training sessions where you'll be in the suit for extended periods.

Putting it on

Take your time the first time. Undo the zip fully and fold the top half of the wetsuit down, zip on the back. Start at the ankles and slowly work the neoprene up your legs in sections —don't try to pull from the top. Smooth out any air pockets as you go, particularly around the lower legs and crotch, before pulling the suit up over your torso. Reaching your hands towards the sky and helps to slide the arm sleeves into place. Use the pads of your fingers throughout, never your fingernails. The Silk-X lining will make this easier than most suits, but neoprene always requires patience on the first few wears. It will get easier as the suit breaks in.
