Product Info

Matt 'Mayhem' Biolos knows a thing or two about baller fin templates. The FCS II MB PC Carbon Medium Tri Fin Set is Matt's signature template that holds it down when opened up and breaks loose right on time.

Product Details


Performance Core CarbonDynamic RTM construction with strategically placed carbon compliments the template and sweep angle of the fin, and produce a bespoke flex pattern with remarkable memory properties. In the water this translates to immediate response when loading up the fins and driving through turns. PCC fins suit fast surfing and are favored by power surfers who like to perform explosive turns on critical parts of the wave.


Fin SpecsBase: 4.30" / Depth: 4.59" / Area: 14.49" / Sweep: 31.7°


Flat FoilA flat inside face combined with a convex outside face. The traditional flat sided foil offers an even combination of drive, pivot and hold and provides a very consistent, reliable feel over a wide variety of conditions.

FCS II Fin SystemThis fin is designed to be used exclusively with the FCS II Fin System, and will not fit in the traditional FCS Dual Plug System.

Matt "Mayhem" Biolos' Signature TemplateDelivers a lively combination of drive, hold and maneuverability. This versatile fin set will feel reliable out on the open face or tight in the pocket.

Ideal ConditionsA wide range of conditions, particularly good in critical overhead waves.

Board TypesPerformance shortboards and hybrid models with the FCS II Fin System.
