Engineered for Speed

The majority of the suit features a highly versatile fabric that offers excellent durability and buoyancy, enhancing overall adaptability.
In areas with the greatest range of motion during swim strokes, we use an ultra-flexible, lightweight material to provide maximum stretch.
The thigh section incorporates an ultra-buoyant fabric, naturally lifting the lower body to promote a streamlined, horizontal posture in the water.

It's designed to generate twice the buoyancy of conventional wetsuits, helping you maintain an optimal body position in the water.
By dramatically reducing drag, it allows you to experience the fastest and most comfortable swim ever.

日本国内でデザイン・設計された3X-SPORTSウェットスーツのロゴ刻印。「Japan Design」の文字

Japan Design

Our wetsuit was born in Japan.
With the precision and meticulous attention to detail unique to the Japanese mindset,
we have pursued every fundamental function to perfection.
This dedication to craftsmanship delivers the speed of a shark to every triathlete.The bold, asymmetrical design—instantly recognizable from a distance—
has become the symbol of 3X.
To wear it is to embody speed itself —
and to command both admiration and awe from those around you.Just like the moment

you spot a dorsal fin slicing through the surface of the sea.
