The Apex is an ideal harness for those looking for both flexibility and good back support. It has a medium rigid flex index of 8. The side parts are flexible, and an internal flex belt allows for good mobility. An EVA pad inside provides cushioning, while the 3D_Plus spine reinforces back support. This creates a balance between freedom of movement and support through a high outline. The harness is lightweight, thanks to its partly Curv construction, non-water absorbent HD_Foam and the sleek Spectre Bar, which includes a kite hook. The Curv_Flaps of the Spectre bar allow for seamless and optimal force distribution throughout the harness.

The Apex also comes with an integrated Kite_Knife Multitool 2.0 and HPL_Slider for added convenience.
