The FCS II Sharp Eye Tri Fin Set, developed by Marcio Zouvi, offers all-around performance with a balanced template and flat inside face for quick response. Featuring updated carbon tissue inlays and AirCore construction, these fins are lightweight, stiffer, and perfect for light-to-medium-weight surfers seeking speed and control. Designed for a range of conditions, they excel in critical overhead and punchy waves, making them ideal for performance and hybrid shortboards.
