The new FLX is designed to suit the seasoned freerider. It is the perfect machine for driving at high speeds or perform spectacular big airs with ease. The board offers a unique blend of speed, power and control which will put a smile on your face in each session.

The freeride optimized shape, featuring a straighter outline and thinner, batwing tips, makes it extremely reliable and versatile in real world wind and water conditions. Due to this special shape, combined with the rocker line, the FLX is quick to plane and can be driven upwind without any effort.

The batwing tips also provide excellent control when riding overpowered. The triple spine design, combined with the quad concave, makes the board very steady and reliable. The board has a smooth glide and even in chop it feels very easy to handle. At the same time it is very stable. The 3D shaped rails improve control and minimize spray. Rider comfort is enhanced by the use of a smooth 3D deck shape.

The FLX is crafted using a full Paulownia wood core plus carbon and biax glass laminate layers and ABS rails. This construction assures a bomb proof durability and makes the board very light. The board comes with HPCF Fins 4 x 40 mm, pads, straps and Molded EVA handle.
