INSTASUP construction uses the same technology and materials as most types of rafts used to go down river rapids. Built with extremely durable PVC fabric layers attached with high strength drop-stitch construction allows these boards to inflate with enough pressure to have comparable rigidity to solid epoxy boards. Our new multi-layer MSL Fusion technology now creates a stronger yet lighter board, allowing up to 20 psi heated inflation (15-17 psi heated is adequate and recommended). Deflation takes only seconds and the flexibility of the fabric allows the customer to roll the board up to fit it into a convenient backpack for ease of transporting or storing. No car rack required, airplane compatible, and urban living efficient.
