The Submarine created an immediate sensation when it arrived on the competition scene at last year's PWC Superfinal. Since then, our team has been refining the design to produce a viable commercial version for all pilots. This revolutionary harness is the result of a 5-year R&D process, which involved wind tunnel research, extensive testing and a prolonged beta phase involving the world's top competition pilots. We believe the final design has proven that replacing your harness with the Submarine will likely result in a larger performance advantage than updating your wing to a newer model.
