The Starlite Kayaks are the first affordable kayaks built durable enough to withstand Class III+ whitewater. Stability and performance are combined in this kayak that is suitable for both technical rivers and scenic lakes. The I-beam air floor is constructed of the same strong 1100 denier material as the side tubes, with 4000 denier floor material (the toughest in the industry). The floor is raised a couple inches, resulting in excellent tracking as the kayak glides along on the two side tubes. Unlike most kayaks, this design provides for ample weight capacity without sitting in water. Adjustable buckle-in thwarts.
