Product Description

The FCS II MH Mason Ho PC AirCore Medium Surfboard Fins are built to reflect Mason Ho’s fast, loose and creative approach to surfing. Designed for surfers who like quick transitions, tight arcs and playful lines, the MH template delivers a lively feel that encourages speed and spontaneity in everyday conditions.

Using Performance Core with AirCore technology, these fins reduce weight through a lightweight internal core while maintaining strength and flex integrity. This gives the board a fast, responsive feel with easy release through turns, making them feel particularly good in beach breaks and more technical wave conditions. Compared to standard PC fins, the AirCore construction helps the board accelerate faster and stay light underfoot.

The Medium size is ideal for lighter to medium-weight surfers, or anyone who prefers a looser, more responsive feel. Fully compatible with the FCS II tool-free system, the MH PC AirCore Medium fins are perfect for surfers who like to surf creatively and keep their approach dynamic and fun.
