The softer RADIUM 7 (flex index 7)* epitomizes support and flexibility. A benchmark product for years, its comfort and overall performance is renowned amongst windsurfers. The elongated shape is designed to spread the load across the back, whilst the additional Archbar/Hyperfoam padding melts away pressure and protects the hip and rib area.

*Flex Index (1-20): The flex index describes the rigidity of the harness.
Higher flex index = hard and rigid = direct feeling
Lower flex index = soft and flexible = comfortable
