ION's new 2021 Sonar kitesurfing harness is a further development of the Radar. It is especially tailored to the needs of racing and foiling. Characteristically, it features a low profile which generates a low center of load transmission. The integrated Curv plate improves force distribution. The revised ergonomic leg straps, inspired by the technology of climbing harnesses, have been developed to enable fantastic freedom of movement and to eliminate any pressure points. The Sonar comes with ION's C_Bar 2.0 which already includes the stainless steel kite hook.
