View full detailsWhy it feels tight: on dry land a right-size wetsuit feels firmly snug — like a handshake everywhere. In the water it eases and disappears. It’s only too small if you can’t breathe deeply or raise your arms overhead.
What buoyancy means: built-in float. This suit lifts your hips and legs so you stop dragging them — for most first-timers that’s worth more than months of training.
Putting it on: dry skin, go slow, and use fingertip pads — never nails. Nail nicks are the #1 wetsuit injury.

Description
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.
