HO's legendary kneeboard reputation continues with the Joker. This kneeboard is compression-molded out of glass and resin, similar to a ski. Symmetric square tip and tail shape give you maximum pop off the wakes. Two-stage rocker design maximizes pop off the wake. Locking edge channels keep you locked in a rail. Dual density kneepad offers greater impact protection and soft, cushy landings. Single locking strap keeps you comfortable and in place during your ride. HO kneeboard has a 1/2" center thickness that tapers off to 1/4" in the tip and tail.
