The FCS2 Mid Series Performance Glass Single Fin has been designed to work across a variety of mid-length models with a 2 + 1 (single box) setup. 
Available in 6.5" and 7.0", both sizes share the same template of a balanced outline, a moderate area through the tip, and a neutral angle that offers a very consistent, smooth feeling. The foil is engineered to have a semi-stiff tip flex to assist with drawing clean, flowing lines on longer midlength boards. 
With an emphasis on glide, the Mid Single has been constructed from solid Performance Glass.

Performance Glass (PG) fins are machine cut from layers of solid fibreglass. PG fins have very fast memory recall which translates into speed. These fins are stiff, providing immediate response and acceleration as the surfer powers up and drives through a turn, while maintaining flex integrity under immense force and in extreme conditions and situations.
PG fins are widely used by pro-level surfers.
