The JOOLA Method CGS 14 Pickleball Paddle has a 14mm core and features a Carbon Grip Surface (CGS), JOOLA's CGS technology utilizes a durable, long-lasting Carbon-Flex 3 textured surface that grips the ball to create more spin. The Elongated Handle gives extra grip length for 2 handed backhands. A thicker core creates more control and stability but less power.
