ION`s 3D Fit Technology provides the perfect fit for each individual`s body size and shape. Your individual fit derives from back length and waist circumference. Therefore the Riot Curv is available in regular and tall sizes. The exchangeable Ergo_Pad on the inside offers optimal lumbar support in two profiles (each harness comes with two options - thin and thick pad - choose what suits you best). The Riot Curv is medium rigid (flex index 14) and offers a good balance between direct feeling, flexibility, and support. An ultra-lightweight Curv construction distributes forces evenly throughout the harness. At the same time, it`s flexible enough to allow for optimum freedom of movement. Non-water-absorbent Hyper_Foam contributes to the overall ergonomic fit and light weight while the internal flex belt provides flexibility in the front. ION`s sleek Spectre Bar (including kite hook) completes the Riot Curv. Its Curv_Flaps create a seamless and optimal force distribution throughout the harness. Comes with integrated Knite_Knife Multitool 2.0. The Riot Curv is the choice of athletes like Matchu Lopes and Gianmaria Coccoluto.
