This solid performer features a parabolic shape for maximum lift off the wake and smooth transitions during any trick. Dual retractable fins allow maximum cutting power when down and maximum trick potential when retracted. Fins may be adjusted between sets, but not while the board is in motion. This board has a contoured EVA pad with 3" padded shock strap. The HydroSlide Pro XLT Kneeboard includes Patent Pending retractable Hydrohook, there when you need it and gone when you don't. Made in USA.
