The Jeff McCallum Acid Keel Fins are part of the Captain Fin Co Limited Especial Collection. The fin was designed by shaper / surfer Jeff McCallum to compliment a retro twin fin fish.
These Keels feature a more laid back profile with plenty of area and rake. The result is a fin that will project you fast down the line giving you loads of drive off your bottom turns into drawn out traditional feeling carves.
Compatible with FCS fin boxes.
