ION Harness Seat Kite Radar
Description
Description
The ION Harness Seat Kite Radar is ION’s versatile seat harness for kiteboarders who want good support, high comfort and freedom of movement all at once. With its combination of stable back support and soft side panels, it’s a solid all-around choice, whether you’re cruising, freeriding or progressing to the next level. The harness is designed to distribute power evenly across your body, so you can stay on the water for hours without pressure marks or imbalance.
The heart of the Radar is its hybrid shell construction: it is partially molded from Curv composite material, providing strong, lightweight and stable back support, while the flexible side panels follow your body’s movements. The ergonomic leg straps are inspired by climbing harness technology and ensure full freedom of movement without pressure points, while an integrated neoprene belt (NEO Belt) adds extra flexibility and twisting comfort. Spectre wing pockets integrate the spreader bar flaps seamlessly into the harness, keeping clothing snug and secure, while HD foam padding and the C_30 buckle contribute to a precise and comfortable fit.
- Hybrid shell construction: Partially molded Curv composite provides strong back support combined with flexible side panels for comfort and power transfer.
- Spectre Bar 2: ION’s latest spreader bar technology with high flexibility, a slim profile and even load distribution – including a kite hook.
- Ergonomic leg straps: Inspired by climbing harness technology for freedom of movement without pressure points.
