FCS II MODERN KEEL TWIN FINS - CLEAR (PERFORMANCE - GLASS)MODERN KEEL TWIN FINS CLEAR (PERFORMANCE GLASS) Overview Upright keel template designed for traditional fish shapes.

High area and depth not only delivers a feeling of control when pushed harder on the open face, but helps to maintain tremendous speed through roundhouse cutbacks.
