Whether you’re a beginner learning your first transitions or a seasoned kitesurfer chasing big air and wave control, this guide will help you find the perfect ION harness for your riding style.
Discover ION Harnesses
ION’s harness collection represents the perfect fusion of performance, comfort, and control. Engineered for all experience levels, the range includes both waist harnesses and seat harnesses, ensuring every rider can achieve the ideal balance of freedom and support.
Your choice begins with riding style and preference. Waist harnesses deliver unrestricted movement, responsiveness, and agility — ideal for advanced riders focused on wave riding, freestyle, or big air performance. In contrast, seat harnesses offer outstanding lower-back support and stability, making them the perfect choice for beginners, freeriders, or anyone prioritizing comfort during extended sessions.
Choose Your Perfect Fit
Within the ION waist harness lineup, you’ll find a wide selection of shell constructions, each tailored to specific performance needs. From soft shell harnesses that offer ultimate comfort and flexibility to rigid hard shell designs built for maximum load transfer and control — and innovative hybrid shell options that combine both worlds — ION ensures there’s a harness for every riding style and discipline.
Each model is the result of cutting-edge research, premium materials, and ergonomic design, offering riders a secure, natural fit that enhances comfort and confidence on the water.

Hard Shell
Fully Curv Construction
Hardshell harnesses provide a stiff, direct riding feel, making them ideal for riders who push their limits with speed and height. All ION Cury hardshell harnesses are equipped with innovative 3D Fit Technology, offering intermediate sizing options and the exchangeable Ergo_Pad to ensure a perfectly tailored, custom fit for every rider.
Hard Shell Harnesses
For riders who demand maximum support and control, ION Hard Shell Harnesses deliver uncompromising performance. Designed with rigid back panels for superior load distribution, these harnesses enhance stability, power transfer, and precision — especially during powered-up sessions and high jumps. Perfect for advanced riders, they offer the ultimate blend of support, responsiveness, and comfort in a sleek, high-performance design.
Construction
Each ION Hard Shell Harness is built with a unique back plate, available in Carbon, Curv, or laser-cut Curv materials. These advanced composites provide exceptional stiffness and durability while maintaining ergonomic comfort. The result is a harness that locks your body securely in place, giving you direct feedback and control, no matter how hard you push. Every material variant offers its own distinct advantages — from the ultra-stiff responsiveness of Carbon to the slightly more flexible feel of Curv.
Weight & Materials
Despite their rigid construction, ION Hard Shell Harnesses remain impressively lightweight. The non-absorbent internal cushioning keeps the harness comfortable and dry, ensuring consistent performance session after session. This thoughtful combination of strength and minimal weight gives riders the freedom to focus on performance without fatigue.
Fit & Comfort
A perfect fit is essential for both comfort and performance. When your harness fits like a glove, you’ll barely notice it’s there — even during long, high-intensity sessions. All ION Hard Shell Harnesses come equipped with the Ergo_Pad, allowing for a tailored fit that supports your spine and enhances overall ergonomics.

This innovative hybrid construction delivers the ideal balance of structure, freedom of movement, and long-lasting comfort, making it the perfect choice for riders who want both performance and ease of use.
Construction
Each harness features a 3D-molded Curv spine, a proven material known for its lightweight durability and ergonomic support.

The harness includes elastic HD_Foam padding, providing a snug, adaptive fit that won’t absorb water. The result is a lightweight harness that maintains its performance and comfort — no matter how long you ride.
Fit & Support
To maximize back support and counterbalance the softer shell elements, all ION Hybrid Shell Harnesses feature a high-profile outline for enhanced stability. Each model also comes with an exchangeable Ergo_Pad, allowing you to choose between two pad thicknesses for customized lumbar support based on your individual spine curvature. This attention to ergonomic detail ensures a truly personalized fit and all-day comfort on the water.
