The File Fifty by Sharp Eye Surfboards, developed with pro surfer Kanoa Igarashi, is engineered for elite performance and unmatched speed. Designed with an agressive entry and exit rocker, this board features deep single concave from nose to tail and low, sensitive rails, giving it a powerful combination of control and speed. The deepest concave between the fins ensures drive and grip through high-speed maneuvers, making it ideal for intermediate to expert surfers in 2-8ft surf.
