JBL Gen 1.5 Longblade Polymer Fins deliver outstanding performance at an unbeatable price. Dive deeper and stay there longer. These fins feature an all new polymer blade that is the best in its class. Much like the flagship Xcelerator Blade, It features a stiff foot base that becomes progressively flexible towards the tip. The reinforced base adds further rigidity to crucial areas. This balance of stiffness and flex ensures that each kick translates to maximum thrust. These superior properties are the result of an exclusive polymer blend that features nylon and carbon fiber. Polymer blades are set at a 22 degree angle, following the natural foot & leg geometry. The classic Gen 1 foot pocket was developed to be a natural extension of the leg. With them, divers are able to propel effortlessly through water. Each pocket features a melding of two thermo rubber stiffness compounds: one for comfort and one for strength. The end result is limited foot fatigue and unmatched power. Side rails offer additional stiffness and prevent water “spilling” over the edges. The end result is a complete fin that channels all power to thrust. Pockets and blades are modular. Secured with screws and blade clips. This allows for smaller storage, easy repairs, and upgrades.
JBL Longblade Polymer Fins are sold as a set.
