ION Harness Seat Kite Sonar
Description
Description
ION Harness Seat Kite Sonar is a performance-oriented seat harness designed for kite foiling and foil racing. Its low profile keeps power transfer close to your body, giving you a direct and precise connection to the kite - exactly what matters when the pace is high on the foil. This harness is made for discerning foilers who demand maximum support, response, and control at speed.
The heart of Sonar is the hybrid Curv construction, which combines rigid hardshell elements with flexible zones. This provides even force distribution with medium flex, so the harness moves with you without giving in to the strong forces of foil racing. Underneath, a lumbar pad supports your lower back by following the natural curve of your spine, while the ergonomic leg straps allow freedom of movement without pressure points.
- Spectre Bar: ION's slim and lightweight spreader bar with a lightweight aluminum kite hook delivers an extremely direct feel.
- Lumbar Pad: Extra padding that supports your lower back and helps you handle the powerful forces of foil racing.
- C_30 buckle: Easy adjustment of the lightweight carbon spreader bar straps.
- Neoprene belt: Improved technical belt that enhances the feeling of flexibility, twist and comfort on the water.
- Kite_knife 2.0 multitool: Integrated safety knife and multitool with Torx (TX20) and PH3 wrench for footstraps and ION's modular hook system.
- Leash D-Ring: Lightweight and durable attachment point for your kite leash next to the spreader bar – can be placed on whichever side you prefer.
- Complete set: Delivered ready to use with spreader bar including hook, kite knife and handle for safety leash.
Technical details: Kite seat harness · Curv hybrid shell construction · Medium flex · 55% polyester · 40% polyamide · 5% neoprene · Spectre Bar including kite hook · Kite_knife 2.0 multitool
