The Apex 8 is designed in collaboration with ION and comes with a partial Curv shell. Its high outline provides optimal back support thanks to a larger area. The design also features controlled rigidity in the centre with flexible sides, resulting in a perfectly balanced harness that offers support and freedom of movement. With a flex index of 8, it is one of the medium-stiff models in the Duotone and ION harness range and has proven to be incredibly versatile. The Apex 8 comes with the C_Bar 2.0, which already includes a stainless steel kite hook.
