The blades are crafted from an ultra-high-performance carbon fiber known for its remarkable strength and flexibility. Utilizing a high vacuum industrial process, the carbon fiber achieves an exceptional density. While the average carbon fiber used in the industry has 3,000 fibers per thread, Cressi's carbon boasts an impressive 12,000 fibers per threadfour times the standard. This results in quadruple the strength, flexibility, elasticity, and kick response compared to other carbon blades available. The threads in this carbon fiber are exceptionally small, with a total density of an unmatched 20,000 fibers per square millimeter. Medium flexibility blade it is perfect if you fish using a boat to move from spot to spot, using a constant weight. 29 degree angled interchangeable carbon blade Modular detachable fin Superior performance Superior comfort Self adjusting foot pocket
