This is our most universal shortboard, a combination of the JM-F and the JM-FS, recommended for advanced surfers. Single concave flows into a double concave/ vee combo through the fins and off the tailblock. The wide point is pulled back slightly for a curvy outline with a wider tailblock and less nose. This board builds speed instantly off the front foot and allows for explosive back-footed moves. Can be ordered for small, average or over-head conditions.
