The Duotone Radium Team Series is a light, strong hardshell windsurf harness made from Thermo Composite CURV, the lightest hardshell material on the market, developed in cooperation with ION.
The revolutionary Thermo Composite CURV material is a totally new innovation in harness development and sets a new benchmark in design and performance. The Radium Team Series offers an outstandingly light yet incredibly robust construction.
The 3D Plus spine and high outline are designed to support the rider exactly where needed most. You can rely on the team’s choice whether you feel like shredding some waves, pushing the limits of speed or just freeriding. It was created with Duotone’s top wave riders and racers over endless hours on the water. The softer flex and high outline combined with Hyper_Foam provide loads of comfort, and the fully moulded EVA and silicone print keep everything in place so you can focus on your riding.
