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

  1. 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.
  2. 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.
  3. 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.
  4. 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.
  5. 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.
  6. 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.
  7. 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.
  8. 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.
  9. 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.
  10. 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.

Reviews

Looks great. Comfortable. Tight in

"Looks great. Comfortable. Tight in the right places. Really good flexibility around shoulders and arms. Also really liked that it came with a bag, hat and googles. Obviously this suit comes at a significant premium over the majority of suits on the market. Still prefer swimming sleeveless but for a colder swim, this was great."

— Matt A. (5/5)

Great suit ! I am

"Great suit ! I am a better swimmer with vanquish! Great buoyancy and very flexible at the shoulders !"

— Sorin M. (5/5)

I love my Vanquish

"The Vanquish puts you in brilliant position in the water to optimise your stroke. The buoyant leg panels perfect close fit & thin fabric around your shoulders make the vanquish one of the best if not the best wetsuit I have every used."

— Lewis (5/5)

Great wetsuit, can’t wait to race in it

"A wetsuit which doesn’t compromise speed or mobility. Having swam in so many restrictive wetsuits, there was none into the shoulders here which gave it the natural swim feel. Easy to take off in transition and would recommended for OW swimming and triathlon."

— Summer (5/5)

Unrestricted arm freedom

"After 3 outings I can safely say that the shoulder range and arm freedom this suit offers is fantastic. The super thin fabric & neoprene offers a snug supportive fit without compromising on movement. I get much better catch feedback because of this and can swim much more freely. My swimming feels effortless and I'm not fighting the suit or having to modify my stoke, it's as close to 'skins' swimming I have felt in a wetsuit. The leg panels offer a lot of buoyancy - slightly more than my 2023 Aspire. This felt odd on the first swim but now its fine. The body panels offer good support and body position in the water. The cuffs are designed for easy removal which works well although be careful not to catch your watch in the thinner fabric. I love swimming in my Vanquish however to keep it in good condition I always take my time and use gloves to put it on - user error could easily damage the suit esp with the thinner arm construction. I've not yet raced in it but I will in a few weeks and look forwards to seeing the results. I advise checking the Vanquish specific size guide before purchasing as the sizing is slightly different to other Zone3 wetsuits. Eg: My Aspire is a Large but I needed my Vanquish in XL and I'm pleased I sized up!"

— Liv (5/5)

Its probably the best wetsuit

"Its probably the best wetsuit that you find on the market currently. Perfect flexibility, excellent moves, true size. Easy to care and store."

— Assen D. (5/5)

Vanquish x

"Very pleased with my Christmas present to myself. Great fit with fantastic flexibility in the shoulders. Looking forward to the new triathlon season"

— David B. (5/5)

I broke a cardinal rule

"I broke a cardinal rule with racing, I bought the vanquish x and my first wear was t100 race, after a major rip in my previous wetsuit by a different brand however the vanquish x made race day nervous vanish, I felt comfortable, it fit like a glove and its performance was top tier, during transition, I was also able to get out of it no problem, I do wish there was speed Zip just to make it that little bit quicker."

— Aaron R. (5/5)

Fantastic!

"Fantastic! Did my first full Iron Man in this suit, it gave me confidence to glide through the water safely and with confidence, it's technically brilliant, well made and I love it. I am women's size 10-12 (usually a 10 but increased upper body and thigh dimensions through training) height 5ft 5in, size M is great for me."

— Melanie H. (5/5)

Very happy. Overall quality in

"Very happy. Overall quality in design an d durability seems great, fit is excatly what they had on the website. Had my first two swims and compared to my old wetsuit (which was very tired!) it has made the swim feel smoother"

— Philip S. (5/5)
