O'Brien Sozo Kneeboard

The ultimate in performance

The Sozo is ridden by nearly ALL the top kneeboarders globally, and it's easy to see why. It's explosive, lightweight, and unbelievably maneuverable. The clean, efficient shape quickly initiates turns, edges well through the wake, delivers a clean release, and is very forgiving. Its Fusion Core gives the board an incredibly light and lively feel on the water that takes it above and beyond any other performance kneeboard on the market. The Sozo pad is state-of-the-art, too. It is extremely supportive, fully customizable, and softens landings like no pad ever seen. It truly is the ultimate board for boat riding.
