About this harness

The Radar is ION's all-round seat harness: a hybrid shell with an integrated neoprene belt and climbing-inspired ergonomic leg straps that eliminate the usual seat-harness pressure points. The low hook point keeps power manageable for schools, strong days and long foil sessions — shipped with the Spectre Bar 2 spreader for even load distribution.
