Supporting the world of 300km/h from the inside. High-performance base layer brand ZEROFIT signs sponsorship agreement with globally active motorcycle racer Kaito Toba.

Background of the Agreement

Motorcycle racing is a sport that demands extreme speed, concentration, physical strength, and judgment.

Riders constantly face immense physical stress from racing in high temperatures, long-distance travel, environments with varying temperatures, and discomfort from sweat.

In a world where even a slight dip in condition can affect concentration and performance, the wear that directly touches the skin must offer high comfort and reliability.

ZEROFIT has consistently focused on the concerns of riders such as "feeling cold, sweat, and restricted movement," proposing innerwear as "another layer of comfort equipment" to be worn under protectors and racing suits. Overseas, we have supported the conditioning of riders competing in harsh environments through product provision and support for motorcycle racers.

The spirit of Kaito Toba's continuous challenge on the world stage strongly resonates with ZEROFIT's brand message, "Set Your Limits to ZERO."

This sponsorship agreement is a partnership to support the challenges of athletes competing globally through our products, and we will support every moment of Kaito Toba's journey to the next stage with ZEROFIT's functionality and craftsmanship.

"Ice Mesh" to Support Harsh Summer Race Environments

Achieves a cooling effect that envelops the entire body by integrating three cooling technologies: "contact cooling fabric," "cooling print," and "mesh structure."

Ice Mesh is summer underwear developed for sports scenes in hot seasons. By combining three cooling functions – "contact cooling fabric," "cooling print," and "mesh structure" – and utilizing proprietary technology that reacts with sweat, moisture, and wind, it supports a cool and comfortable wearing experience even in hot environments.

Motorcycle racers wear racing suits and protectors for extended periods, creating an environment where heat and sweat tend to build up inside the suit. Stickiness and stuffiness from sweat affect not only comfort but also concentration.

Ice Mesh is designed for comfortable wear as innerwear for racing suits, as it has good skin-away properties even when sweaty, and the mesh structure on the back allows for easy ventilation of stuffiness. It supports condition management throughout the race week, including during rides, pit waiting times, and travel.

Will be worn at the 24 Hours of Le Mans (Round 2 of the FIM Endurance World Championship) in Spa-Francorchamps, Belgium on June 9, 2026.

Kaito Toba's Comment

I am extremely pleased to be able to work with Eon Sports through the "ZEROFIT" brand.

In motorcycle racing, we compete in various conditions, from high-temperature environments in midsummer to regions with large temperature differences.

In such environments, it is crucial to maintain a comfortable state that allows riders to concentrate on the race and riding.

ZEROFIT products combine high functionality and comfort, making them excellent as innerwear worn under racing suits.

They support comfort even in harsh environments, making them indispensable from daily life to training and racing.

I am grateful for this opportunity and will continue to challenge myself on the world stage with ZEROFIT, working to convey the brand's appeal to as many people as possible.

Furthermore, I will dedicate my full effort to mutual growth and enhancing our value.

Eon Sports Co., Ltd.

Eon Sports started in 1990 with the manufacturing and sale of golf clubs. We established a solid position by developing "flying clubs" with unique technologies that cannot be achieved through mass production, such as composite drivers and the "Tight Neck Shaft®" with an extremely narrowed shaft tip.

What has been consistent since our founding is the spirit of "meticulous craftsmanship" – "to create only what we truly want to use."

Currently, this philosophy extends beyond golf to everyone who loves sports and the outdoors.

We deliver products that are "fun, functional, and cool," centered around the golf club brand "GINNICO" and the functional wear brand "ZEROFIT."

Making sports more enjoyable and comfortable. The essence of our craftsmanship lies in fusing safety and functionality to support that experience.
