The Freeline Twin is a high-performance twin-fin Jack has been refining since 2017 — originally built for a few locals chasing that fast, skatey twin-fin feeling in a more responsive, everyday shortboard shape.
The bottom runs with a slight vee entry and just under flat through the front foot, blending into a double concave with vee out the tail for control and rail-to-rail responsiveness. A slight fluted rail just ahead of the fins subtly lifts the rail line and adds grip through turns. Combined with a tighter tail outline and rounded pin, the board offers a sharp, connected feel without losing that loose twin fin freedom.
Fast, lively, and tuned for everyday surf.
