The ultimate footpocket meets the ultimate composite blade. Meet the second generation JBL Polymer Longblade Fin.

When designing the second generation polymer longfin we set out to create something with the performance of our flagship Xcelerator fins but at a cost for everyone. To accomplish this we went back to the drawing board. We created an all new blade made from a proprietary carbon – nylon blend that replicates the properties of its carbon cousin. Its reinforced base is stiff and responsive. From there it becomes progressively thinner and more flexible, allowing for maximum energy transfer.

We mated this amazing blade to our newly developed tri-density foot pocket. It features three unique rubber blends that work together to create a pocket that is stiff, responsive, and soft in areas where it matters most. The end result is a performance freedive fin that kicks well above the competition.

Pockets and blades are modular. Secured with screws and blade clips. This allows for smaller storage, easy repairs, and upgrades.
