Drop stitch fabric construction is what allows an inflatable SUP to maintain its shape when it is inflated to high pressure. Without drop-stitch, the board would bulge out in the middle like an over-inflated air mattress. Using tens of thousands of tough polyester threads, drop stitch fabric lets us build inflatables with flat surfaces that can be inflated to rock-hard rigidity. You get hard-shell performance along with the easy transportation and storage of an inflatable. Drop stitch fabric SUP boards use the toughest drop-stitch materials in the industry. Sidewalls use two PVC layers specifically manufactured for superior air holding. Unlike typical PVC tarpaulin, the specialized sidewall material features internal fibers coated in liquid PVC before incorporation with the outer PVC layer, making the layers more durable and resilient than ever before.
