What Yamaha Say:
Introducing Yamaha Inpres DriveStar Fairway Wood, The newest Japan Only Inpres series. Overwhelming flight, straightness, and high trajectory

Benefits:

• Uses New Material [X37] - High repulsion performance and tolerance. Adopts a new material "X37" that has high strength and tenacity and allows for more precise design. High repulsion performance produces surprising flight distance.
• High trajectory and stability enabled by "X37" x "Carbon Crown" - It flies straight with a high trajectory. The combination of "X37" monolithic casting and carbon crown achieves a center of gravity height of only 19mm, which is the most important for a club that hits from the ground. An FW with a high trajectory due to the low center of gravity and excellent tolerance due to the high moment of inertia was born.
• "Good Face" - Clubs with a large moment of inertia generally tend to have a large projected area, but inpres DRIVESTAR has an orthodox shape that golfers can easily hold.
