Based on the Lost... Hydra, this little sea monster is designed around an almost traditional Fish outline, melded with the innovative design details of a far more progressive outline, for sizzling snap and power in the pocket. Featuring hand painted monster art by none other than Ryder Biolos, the Rydra will fly when other boards leave you dry.All ...Lost boards contain an exclusive “Progressive Rocker” concave through the length of the board. This Progressive Rocker concave is closely related to surfboard construction allowing for a reactive and performance based pump feature while skating.*Compatible with Carver 68mm Mag, 69mm Concave, and 70mm Mag wheels*
