From the web site.....
The multi-layered hull of the Commander 120cx Limited is the first kayak ever to be infused with Innegra S, the lightest, high performance fiber available. This ballistic grade material is used in the most demanding of applications, from body armor to Formula One racecars; and now it finds a home on the water. This translates into an extremely stiff and lightweight hull, which offers maximum responsiveness on the water.
To achieve the style mandate, nearly every detail of the production model Commander 120 has been overhauled with premium trim materials. On the canvas of the glossy, black composite layup, picture richly stained, hardwood rails along the top rim of the boat, complemented by stained, hardwood carry candles on the bow and stern. Sleek, silver/gray Commander 120cx logos on the stern and accessory bags announce the boat without being ostentatious.
So it is a composite......of multiple layers...
But for 5000 it might clean your fish and pluck your ducks.......
