Overview

Board Types
Fin Family
My fins feel sturdy, fast and predictable with a great projection out of the lip, and plenty of control when pushing your board hard through a turn” – Julian Wilson
Performance Core + AirCore
Fins with AirCore Technology feature a pressed polyurethane foam core that mimics the geometric foil of the fin.
AirCore technology reduces the amount of fiberglass required in the RTM moulding process making it much lighter while allowing total manipulation of the flex.
