Key features

Aerobar Webbing Configuration

The Aerobar is a modular spreader bar platform, with interchangeable connection options depending on your riding style. The durable reinforced nylon body and stainless steel hardware provide direct feedback, with built-in comfort thanks to the EVA molded bar pad. The webbing version features a dual Latch-Lock mechanism, which is installed on both sides of the spreader bar to allow easy and instant entry and exit. The webbing buckles are compatible with all harnesses with 25mm and 40mm webbing slot options. Depending on your watersport of choice, the interchangeable connection system gives you the opportunity to choose between a rope slider, or an industry standard stainless steel kite or windsurfing hook.

Intermediate Flex Curv Shell

Known for it’s light weight and durability, the intermediate flex Curv shell distributes the load from the stiffened center lumbar support section into the flexible outside edges.
