Futures Son Of Cobra Fiberglass Twin Fin Set

Engineered for deep concaves and full-throttle post-modern twin performance. Custom-designed by Paul Lefèvre at Son of Cobra, this signature set is specifically built to complement boards with pronounced double concaves, like the ...Lost x Son of Cobra "Cobra Killer."

Constructed from solid Fiberglass, these fins feature an increased 7.5-degree cant angle (compared to the standard 4-degree twin cant) to help the board roll smoothly onto rail and hold engagement through high-speed turns. Balanced height and base dimensions deliver maximum down-the-line projection, while a thinned-out tip offers immediate springback and effortless release off the top.
