2025 Ion Sonar Foil Seat Harness
Curv Hybrid Shell Construction
The Sonar seat harness is crafted for sophisticated kite foilers who demand top-tier support and responsiveness at high speeds. Similar to the Radar, it features a hybrid shell construction that combines rigid hardshell elements with flexible sections, but with an even lighter build. Equipped with the new Spectre Bar 2 for optimal load distribution, the Sonar also includes a specialized lumbar pad that provides extra support and comfort for the lower back.
Additional features include a C_30 buckle, HD foam padding, a Neo belt, and an integrated Kite knife multitool for safety. Adjustable webbing connects the leg straps to the spreader bar and keeps the hook in a low position. Designed for advanced riders, the Sonar delivers unparalleled control, support, and agility, making it the ideal choice for high-speed foiling.
