FCS II AirCore 5 Fin Set Medium

  • Sale
  • Regular price $165.00

The Al Merrick template has a wide base for drive off the bottom, more rake for big carves, a finer tip for release off the top, and the signature smaller center fin frees up the tail.

Fins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric foil of the fin. AirCore technology reduces the amount of fiberglass required in the RTM moulding process making it much lighter while allowing total manipulation of the flex. Having a stiffer flex, these fins will also perform exceptionally well in steeper parts of the wave and provide a feeling of control when laying a hard rail turn.

Comes with 5 fins so you can ride as a thruster or a quad!  The 5 fin set allows you to customize the performance of your board.  The thruster offers exceptional drive off the bottom and quick tail release, the quad set is ideal for riding the barrel and smooth carves on the open face.

Fits FCSII screwless fin system.
