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 Sol 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 - medium and high support - choose what suits you best). The Sol Curv is medium rigid (flex index 11) 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 lightweight while the Neoprene_Belt provides flexibility in the front. ION`s sleek Spectre Bar (including kite hook) completes the Sol Curv. Its Curv_Flaps create a seamless and optimal force distribution throughout the harness. Comes with integrated Knite_Knife Multitool 2.0. The Sol Curv is the choice of athletes like Mikaili Sol and Rita Arnaus.
