The JOOLA Method CGS 12 Pickleball Paddle has a 12mm 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 thinner core creates more power but less control and stability.
