Chemistry Twin Fin. A collaboration model with graffiti artists and the versatile Chemistry Surfboards crew. This twin fin model is designed with a wide base, moderate rake, and medium-sized tip, based on their highly-regarded thruster collaboration, which is praised for its high performance in all types of waves. They wanted to reflect the versatile feel of the thruster model in the twin fin as well. In other words, this twin fin is high-performance, works in all waves, and is a lot of fun. Recommended fins for modern high-performance twins. Price: ¥16,720 Brand: CAPTAIN FIN CO.
