The HS 4.2" Splayed 80/20, designed by Hayden Cox, is a large sized quad rear set. This unique set of rears features Hayden's unique 80/20 foil with splayed tips. The top inch of the fin tweaks out toward the rail, creating a looser feel for the relatively large size template. Looking to turn your favourite thruster set into a Quad? This pair of Quad Rears can be combined with any Futures front fins to suit your riding preference, board design and waves.
