The parabolic Razorback kneeboard from Hydroslide has it all! 3” padded Shock strap, Patented Thin-Profile design, shift on the fly retractable fins, deep padded kneewells, and the Patented Hydrohook. Whether you have the fins down for slalom like control, or the fins up for surface 360’s, this board does it all. Includes Hydrohook pops up when in use, and then automatically retracts so there is nothing to bang, bruise, or cut yourself on. Made in USA.
