S-Boss / Mannkine 5'10"

S-Boss / Mannkine — 5'10" x 19 1/2" x 2 5/8" — 31.4L

Firewire’s most user-friendly performance board — designed by Kelly Slater and Dan Mann to make high-performance surfing feel accessible, fast, and ridiculously fun. The S-Boss blends a relaxed rocker, fuller outline, and well-distributed volume to give you paddle power, stability, and speed without sacrificing that sharp, modern shortboard feel.

The refined rail line and hybrid 5-fin setup let you tune the board to the conditions — ride it as a quad for flow and speed, or as a thruster when you want tighter, more controlled turns. Built to help surfers of all levels push their progression.
