Designed by Matt Biolos with input from Lost team riders, the MB fin is a powerful addition to the Carver family. Its wide base and tapered tip provide drive, stability, and agility for powerful surfing and smooth turns. Ideal for open-face waves and boards with higher rocker, it balances drive, power, and release. The PC AirCore construction adds stiffness for enhanced speed and control, while the quad setup offers stability and seamless performance for hybrid and performance boards.
