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.

Curv_Spine 3D molded spine made of tried and tested Curv for extra ergonomic back support.

Lightweight Light but durable construction combined with a clever mix of materials.
