  • Unparalleled buoyancy

    The 3X wetsuit uses Yamamoto Chemical Industry's reliable and trustworthy neoprene material "yamamono#39 Super Light ", achieving the highest standards in strength, buoyancy, and flexibility. In particular, the buoyancy has been raised to a new level thanks to the unique expandable panel structure.

  • Stable posture in water

    3X Panel Material Structure
    The panel construction of 3X is designed to
    naturally align your underwater posture
    parallel to the water surface.
    By reducing drag, it helps you achieve
    higher speeds and greater energy efficiency—
    delivering peak performance with every stroke.

  • Practical Experience

    In the design process, we researched the key factors that contribute most to speed in a wetsuit. Based on actual competition experience, we have meticulously refined every detail to deliver a high-end finish that thoroughly supports athletes.

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.

Double the Buoyancy. More Speed.

The high-buoyancy panel positioned at the thighs of the BOOST WETSUIT is a specially engineered feature that delivers next-level lift.
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.

Speed ​​& Buoyancy MOVIE

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.
