The Alkali x Big Sun Flex is a sleek, heavily raked flex fin great for wide arcs and a finely tuned response. Perfect for mid lengths, but also a favourite on the log.
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.
