The C4 Waterman iSUP Sub Vector Stand Up Paddleboard 8-1 is designed for the beginner to intermediate paddler under 150 lbs. The iSUP Sub Vector features progressive rocker that is great for surfing and river riding. Includes deck pad, pump, repair kit, travel bag and board strap. All C4 iWaterman products are fabricated from heavy-duty, military-grade, double-wall PVC material. Inside each product, thousands of high-tech fiber cilia anchor the deck to bottom, allowing for superior rigidity and locking in C4's proprietary rockers, features that grant never before seen durability and the closest thing to hard board performance of any inflatable surf-craft. Unlike brands that use only glue on their seams, the iWATERMAN products are finely stitched with 30% additional thicker, high-tensile fiber thread, making them much tougher, stiffer, and able to withstand a higher PSI (pounds per square inch) of inflation, ranging from 14-18 PSI.
