NEW RELEASE: Mick Fanning's specialty twin takes aspects of the revolutionary H4 and Mick's wildly popular signature thruster to combine into a highly tuned twin form, built for speed and control.
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 molding process making it much lighter while allowing total manipulation of the flex.
