What materials are the Firefly and Lagoon models made of?

The outside cover is made with two different materials; the topside is a high-denier Polyester with a PVC laminate, while the bottom (Hull) is made with extremely durable PVC tarpaulin.
PVC tarpaulin is made by combining two sheets of vinyl with a fabric mesh in the middle.

The perimeter of the cover is electronically welded so that it is watertight.

The inflatable tube is made of heavy-duty PVC. When the tube is inflated the outer cover, which does not stretch, takes form and the kayak becomes rigid.

The seats are constructed using a very durable 420D Nylon Rip-stop fabric with a Polyurethane coating. This offers comfort and support. The seats will float should they happen to get outside of the kayak.
