The Sonar is performance-oriented and especially tailored towards the needs of kite foiling/foil racing. Characteristically, it features a low profile which generates a low center of load transmission. The hybrid Curv construction improves force distribution with medium flex. On the inside a lumbar pad offers back support by following the natural curvature of the spine. Ergonomic leg straps allow for freedom of movement without pressure points. ION`s sleek and lightweight Spectre Bar (including kite hook) amps up the direct feeling even further. Adjustable webbing connects the leg straps to the spreader bar and keeps the hook in a low position. Including Kite_knife 2.0 multitool.
