The Jade is the perfect harness for every windsurfer who's looking for flexibility combined with good back support. With a flex index of 6, it belongs to the medium to soft harnesses. Flexible side parts and an internal flex belt allow for good mobility. An EVA pad on the inside provides cushioning while the 3D_Plus spine reinforces back support. The result is a sound balance between freedom of movement and support through a high outline. The harness comes with a lightweight thanks to the partly Curv construction, non-water absorbent HD_Foam, and the sleek Spectre Bar (windsurf hook included). The Curv_Flaps of the Spectre bar create a seamless and optimal force distribution throughout the harness.
