The FCS II Matt Biolos PC Carbon Tri-Quad Fin Set was designed by revered shaper Matt "Mayhem" Biolos. Same proven template with a new look. The MB template offers freedom to perform tight turns in the pocket with an emphasis on speed. Sitting in the reactor family, the MB is considered a high performance fin because it responds incredibly fast, but still offers enough control so you can confidently lay into a turn with plenty of force. Ideal for a wide range of conditions, particularly good in critical overhead waves. Designed to fit the FCS II Fin System and recommended for performance shortboards and hybrid models.
