Retro Fish - The last few years have seen an explosion of Retro Fishes of both the classic Twin Fin set up and the ever more popular Quad Fin. Either way you slice it, Retro Fishes are flying off the shelves everywhere, and for good reason. Retro Fishes offer exceptional speed and maneuverability, classic wave riding charm, and fantastic wave catching ability—even in small surf. Intermediates looking to switch to a short board and experts looking for a fun summer fling will not be disappointed with the Performance; Classic Style dripping off the swallow tails of these Equinox boards. Oh yeah, don’t forget your OP’s and your tank top on the walk out to your VW Bus .  Curious abut the differences between Twin Fin and Quad Fin???
