What Yamaha Say:
Introducing Yamaha Inpres DriveStar Utility, 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. Uses a carbon crown. Achieved a 1mm lower center of gravity than the previous model. Furthermore, by adopting a stainless steel material with a heavy specific gravity for the body, a UT with a high moment of inertia was born.
• "Good Face" - The inpres DRIVESTAR has a shape that is easy for golfers to hold while maintaining the tolerance of the wood-type utility.
