    Building on the legacy of its high-performing predecessor, the new Tsunami 4.0 swimskin delivers cutting-edge speed and efficiency in the water, now presented in the same signature color as our Fjord 4.0. We've taken the already exceptional Tsunami 3.0 and implemented key refinements to further enhance your performance on race day.

    The Tsunami 4.0 continues to utilize the advanced technologies that set the 3.0 apart. At its core is the exclusive Tridium (3Dium) fabric, developed in Milan with the industry's leading manufacturer of performance swimwear. This innovative material features a hexagonal 3D texture, a layered scale array inspired by our proprietary X-Skin. This unique construction leverages the boundary layer phenomenon to delay laminar flow separation, significantly decreasing drag – the most effective way to increase your speed in the water.

    Crafted in Italy with the highest quality materials and meticulous attention to detail, the Tsunami 4.0 maintains the strategic seam placement and orientation aligned with the direction of travel to minimize drag and maximize comfort. The advanced base fabrication and coating provide unparalleled speed with a near-zero drag coefficient and a subtle buoyant effect.

    For the 4.0 iteration, we've fine-tuned the fit of the suit. This adjustment creates an even more hydrodynamic profile, allowing you to move through the water with reduced resistance and improved efficiency. Coupled with the striking new design the Tsunami 4.0 is designed for those who demand both top-tier performance and a distinctive look.

    The same great speed skin, now evolved for even greater speed and style.

  • 1. How long will Purpose gear last with consistent triathlon training and racing?

    All Purpose products — especially those with Hypermesh Pro — are built to endure the grind of serious triathlon prep. With proper care, they’ll hold their performance, fit, and structure through multiple seasons of racing, travel, and long training blocks.

    2. What makes Purpose Performance Wear stand out in triathlon and endurance sports?

    Purpose was made for athletes training in real-world conditions — heat, humidity, and high mileage. Hypermesh Pro fabric is lightweight, breathable, and fast-drying, offering race-day performance without compromising comfort. It’s trusted by elites across Asia and beyond for a reason.

    3. How should I care for my Purpose gear after a session or race?

    Rinse your kit right after training, then cold wash on a gentle cycle. Avoid softeners, bleach, and the dryer — hang dry only. The gear is tough, but a little care keeps the technical fabrics performing at their best.

    4. How does Purpose gear fit — is it true to size?

    Purpose is performance fit — streamlined, aero, and made to move with you during swim, bike, and run. It’s meant to feel close to the body without restricting movement. If you prefer a slightly looser feel or are between sizes, sizing up is a safe call.
