The Radium Team series is ION's professional windsurfing harness model. It provides a direct kit feel, as well as excellent back support thanks to its high profile and partial Curv shell. Another feature of the premium line is the new Spectre Bar, which stands out for its direct power transmission, light weight and aluminum windsurfing hook. Flexible side sections guarantee maximum freedom of movement for the rider. In addition, EVA panels on the inside prevent chafing, while the hydrophobic Hyper_foam guarantees a perfect fit and ensures lightness even during the longest sessions with multiple visits to the water. Tested, approved and used by world champions Marc Paré and Victor Fernandez.
