The Advanced Elements high pressure drop stitch floor is a great add-on accessory that extends the range of many Advanced Elements kayaks. The 4-6 PSI floor adds rigidity, providing better paddling performance. See our detailed review using the High-Pressure Drop Stitch floor for the Convertible kayak versus the standard 1 PSI PVC floor. Drop stitch floors are available for the AdvancedFrame, Sport, Lagoon2, DragonflyXC2, Expedition and Convertible models.
