The ono weed fin is the world first weed fin specifically designed for freewave and freeride boards between 90-110 liters. We took the best from our blade weed Halalua fin and blended it out the best characteristics of our MANO weed wave fin. Louis the engineer behind MAKANI has invented a new way to design the fins and he is now able to change the thickness of the fin exatly where it is needed to give the fins the exact flex where we want it. The result is a perfect compromise between speed, upwind and maneuverability, speed and comfort. The top area is stiff for easy upwind. A nice cutout for slashy jibes and super flexy tip for those gnarly bump and jump conditions.
