PRGR fully remodeled the "RS" series into a version that more intensively pursues flight distance and ease. All the clubs adopted the design concept called the "Double Crown design." To achieve greater flight distance, the GiriGiri high-initial-velocity area of the driver was further enlarged compared with the conventional ones, and consist of two models --the "RS", which drives the ball with draw and the "RS F", which drives the ball with fade--were developed. The fairway woods, utilities, and two iron models are designed for greater distance and ease with the enhanced resilience performance at the lower portion of the face, which is the main striking area of amateur golfers.
