The Insanity Carbon Adjustable is the result of years of research and development with new materials testing strength and durability without sacrificing weight and performance. We think you will be amazed with how light and strong our Insanity paddles are. The impact resistance of the polypropylene carbon blade is excellent while still retaining the thin light performance design. The Insanity blade has a powerface dihedral and the PowerARC™ which provides a clean and aggressive catch. The adjustable shaft uses the LeverLock system with 16 inches of adjustability and provides a graph to match your height to the paddle length. Assembled in the USA.
