Product Construction
Performance Core + AirCore
Performance Core (PC) fins are made using a multi-layered resin transfer molding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light, and can be used in a variety of different conditions.
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.
Additional Info
"The fins have been all time!!! Got some crazy waves at Ala Moana and got to push them hard as I could in the big bowl on some turns; full control off the bottom and nice and loose off the top. They went totally crazy in the pool as well, great projection on the air sections." —Mason Ho
Mase is calling this his new magic fin!
The new Mason Ho signature fin is a mash up of different templates. We took influences from Kelly Slater’s original K-3 and Mick Fanning’s signature templates, then reworked the flex, foil and tip profile based on extensive testing and feedback from Mason himself. This might just be the fin to rule them all...
Sitting in the Accelerator Family, this all-purpose, all conditions fin will feel steady when driving into a turn, and fast and loose off the top. Explosive is another word to describe how this fin responds, and in this case, the personality of the M.Ho fin totally matches the creator and rider. Fast, Loose & Fun
Mason’s fin features a bevelled leading edge which allows for silky smooth transitions between turns. Performance Core + AirCore construction makes the fin a touch lighter, the flex a little stiffer and overall more reactive compared to standard PC construction, which is again suited to Mason’s punk style of surfing.
This fin had a long development runway. Mason was after one fin he could use in his small wave rock hopping fun boards right through to his big wave pipe guns, and it wasn’t until he was totally satisfied that we pulled the trigger.
Welcome to Mason’s world, welcome to Mason’s new fin Steady off the bottom, fast and loose off the top. Suited to a wide range of conditions, from small beachies to big bowling reef breaks. Ideal for surfers looking for a dependable, one-quiver fin.
