• 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.

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.
