Patented "On the Fly" retractable fin system allows you to drop the fins for
hard carving action, or raise them for quick 360's, all without having to stop
riding. Molded pad with deep knee wells for maximum control. Patented Hydrohook
allows anyone to get up on a kneeboard the first time, with no strain on their
back or arms. The Hydrohook retracts flush with the deck when not in use, so
there is nothing to bang, bruise, or cut yourself on. 3" padded strap and deep
EVA knee wells give you great control during it all.
