2021 Ion Apex Curv 13 Harness

The Apex Curv 13 features ION's revolutionary thermal composite Curv material known for its light weight and great durability.

With a flex index of 13, all loads are distributed perfectly through its stiff 3D pre-shaped center part. Together with the high outline, this medium-stiff to stiff harness supports the rider exactly where needed. Flexible side parts allow great freedom of movement for radical moves on the water. The Apex Curv 13 was also equipped with ION's popular C_bar 3.0 and Kite_Knife Multitool 2.0. The C_Bar 3.0 includes a dyneema webbing slider and comes without hook – allowing you to choose between ION's hook options to fit your personal preferences. The hook must be purchased separately.


Key Features of the 2021 Apex Curv 13

Curv 3D molded spine made of tried and tested Curv for extra ergonomic back support.

Inside EVA EVA on the inside prevents the harness from riding up and rotating.

C-Bar 3.0 Comfortable and lightweight with a sleek design – the C_Bar 3.0 Slider unites all these properties into a single piece of equipment. For durability the rope was replaced with robust Dynema Webbing that you'll often find in rock climbing gear. Molded EVA on the inside provides a comfortable fit and contributes to the slim design. On top, the tension lever system allows you to quickly and perfectly adjust the webbing.

Ultra lightweight Thanks to its light construction combined with a clever mix of materials, this harness ranks as the most durable and lightweight hard shell on the market.

3D Plus Spine The Curv harness range comes with a three dimensional version of the Plus Spine feature, which results in an even stronger back support. 

C30 Buckle Easy to handle carbon adjustment of the spreader bar webbings with a pleasantly light weight. 

Hyper Foam A viscous elastic foam that creates an ergonomic fit without sucking water.

Internal Flex Belt A flexible closing belt system on the inside guarantees a snug fit and adapts perfectly to the rider's individual anatomy.

Kite Knife 2.0 Multitool Multitool including double bit with 3/32 hex key and PH3, can be used for fins, footstraps, and the modular hook system of ION's C-Bars. 

HPL Slider Stainless Steel ring attached to the handle pass leash to connect to your safety leash -- guarantees a smooth sliding of the latter.
