The Radium Curv 13 features ION's revolutionary thermal composite CURV material known for its light weight and great durability. With a flex index of 13, all loads are distributed perfectly through its stiff 3D pre-shaped center part. Together with the high outline, this medium-stiff to stiff harness supports the rider exactly where needed. Flexible side parts allow great freedom of movement for radical moves on the water. On top, the Radium Curv 13 is equipped with ION's popular C_bar 3.0. The C_Bar 3.0 comes with a lightweight windsurf aluminum hook.

• 3D_Plus_Spine - The Curv harness range comes with a 3-dimensional version of the PLUS_Spine feature, which results in an even stronger back support.
• C_30_Buckle - Easy to handle carbon adjustment of the spreader bar webbings with a pleasantly light weight.
• Hyper_Foam - A viscous elastic foam that creates an ergonomic fit without sucking water.
• Internal Flex_Belt - A flexible closing belt system on the inside guarantees a snug fit and adapts perfectly to the rider’s individual anatomy.
