FactorX - The driver that delivers the greatest distance of your life.

A driver who has both the initial speed and operability that can be played strongly like a high-resilience club.

For over 20 years, HAL Sports Production has pursued the mechanism of flight distance achieved by top players.
Hal Tsunezumi, now 66 years old, sought to maximize his own distance through years of research with master craftsmen for each component. The answer he arrived at was a simple truth: "The ultimate distance is achieved by executing maximum head speed combined with a perfect impact at the center of the face."
The Factor X, which realized a staggering performance improvement by increasing Hal's distance by 40 yards at age 66, is an innovative driver designed with a thorough pursuit of lightness and ease of swing.

The Factor X was featured and tested on Professional Shinichi Yokota's official YouTube channel.

Pro Yokota was impressed: "This is the best club!"

On the day of the test, the driving range was freezing (it had snowed the previous night).
The conditions were harsh, making it difficult even for a professional to move their body. However, despite these conditions, the moment he swung the Factor X...

"Easy! It flies so far! This is the ultimate club as you get older."

Pro Yokota took a liking to the Factor X 10.5 degree model.
He gave it his seal of approval for its "easy-to-hit functionality" and the surprising numbers it produced, even before he was fully warmed up.

The Factor X has an incredible backstory: its developer, Hal, increased his own distance by 40 yards at age 66. This overwhelming performance has now been clearly proven through testing by the theoretical expert, Pro Yokota.
