ION Radium is the ideal men'swindsurfing harness for anyone looking for flexibility combined with good back support. With the Flex Index 8/20, it features moderate stiffness. Ultra light construction. Curv Hybrid Shell with strong back support and flexible sideparts. 2 exchangeable pads included.
The Radium is the ideal harness for anyone looking for flexibility combined with good back support. With an elasticity index of 8, it features moderate stiffness. Elastic side sections and an internal elastic strap ensure good harness hold and high mobility. Developed with the rider's health and comfort in mind, the Radium has an interchangeable Ergo_Pad inside. This system allows you to change the degree of back support thanks to pads of different thicknesses. They prevent lower back injuries, reduce pain caused by prolonged swimming and increase comfort. 3D_Plus Spine reinforces back support. The result is a good balance between freedom of movement and support thanks to the high contour of the waist. The Radium is very lightweight thanks to the non-absorbent HD_Foam and the elegant Spectre Bar pad hook (lift hook included). The Spectre system's Curv_Flaps ensure even, optimum force distribution throughout the harness.
FLEX INDEX (1-20) describes the rigidity of the harness
Higher flex index = hard and rigid
Lower flex index = soft and flexible
