George Greenough the eccentric visionary that was the first to explore the steepest parts of the wave on his handmade kneeboard craft. Known for modelling board fins off tuna dorsals and being pivotal in the short board revolution.
The Alkali x Big Sun is modelled off Greenough's famous shape. With a perfect balance of drive and release, this may be the most versatile and effective single fin template ever.
Alkali Fins are 100% high quality. Details include a solid brass pin and stainless steel plate and screw. They are hand made from hand foiled fibreglass straight from their Ballina factory on the Gold Coast of NSW, Australia.
