ION Riot Curve Kite Waist Hardshell Harness

The Riot Curv redefines performance, delivering maximum support, optimal control, and freedom to push your limits.

Now equipped with the brand-new Spectre Bar 2, this harness features a lightweight yet ultra-strong hook plate that enhances load distribution and enables precise control.

Constructed with ION’s exclusive CURV® composite material, the Riot Curv achieves the ideal balance of stiffness and flexibility, offering reliable support for progressive riding while preserving full freedom of movement. With 3D Fit Technology, riders can dial in the perfect fit thanks to intermediate sizing options and an exchangeable Ergo Pad in two thicknesses, allowing for true customization based on body shape and riding preference.

The ergonomic 3D Plus Spine design further supports the spine without restricting motion, while the low-profile outline molds seamlessly to your body. Top professional athletes like Matchu Lopes and Noè Font call the Riot Curv their own.
