ION's harness ergonomics provide the perfect fit for each individual's body size and shape. The harness outline derives from body height and girth, ranging from high to low with intermediate 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 and HPL_Slider.
