The Apex Curv 13 Select is by far the lightest and most durable hardshell harness on the market featuring ION's revolutionary thermo composite CURV material. Thanks to high-end add-ons like the C_Bar 3.0 (Hook/Webbing Slider), Double D Buckles and Kite_Knife Multitool 2.0, the Select level stands out from the crowd. With a flex index of 13, all loads are distributed perfectly through its rigid 3D pre-shaped center part. Together with the high outline, this medium rigid to stiff hardshell harness offers all the comfort any dedicated kiter could wish for. Flexible side parts allow the rider to move and twist freely. Additionally, inside EVA prevents the harness from riding up while non-water absorbent Hyper_foam contributes to outstanding comfort for extra-long water action.
