Before the Inflatable Kayak often make with 0.9mm PVC Tarpaulin, but these years, some clients tell us the PVC is easy to damage and have holes. So our clients suggest us to change the PVC instead of Drop-Stitch materials, and they have tested it in EU and come back to us very good quality, even easy to use, more stable than PVC. This is a good chance for us to test new products, if you have any new ideas, just let us know, we are open heart to work together.
