About this harness
The Sonar is ION's performance seat harness: an evolution of the Radar tailored to foiling and race-foiling, with a deliberately low profile that drops the centre of load transmission where racers want it. Partly Curv construction stiffens force distribution and back support — the seat harness as a performance instrument.
