Mystic Harness Lineset Griplock Handles

The Mystic Harness Lineset Griplock Handles is an elastic harness line designed to connect a wing with hard handles or a boom to a waist harness or harness belt. Made by Mystic, a Netherlands-based watersports brand with a long track record in kiteboarding and wing foiling accessories, this lineset uses a Dyneema SK78 outer sleeve wrapped around an elastic core. The elastic construction keeps the line taut and in a fixed position on the handle or boom, while still allowing it to slide for freedom of movement when hooked in. The Griplock mounting system is built for quick attachment to rigid handle setups.

The product is available in six lengths — 22", 25", 28", 30", 32", and 34" — letting riders dial in the distance between their harness hook and the wing based on arm length and riding preference. Shorter lines suit riders who prefer the wing closer to the body, while longer options provide more separation and leverage.

This harness line targets wing foilers and wingboarders who ride wings equipped with hard handles or boom setups and want to hook into a waist harness for power transfer. Mystic positions the elastic design as particularly suited for freestyle-oriented riders, since the stretch helps maintain the hook-in connection during dynamic movements like pumping for power, executing jibes, or performing tricks where the distance between rider and wing fluctuates.

Riders at an intermediate level and above who have progressed past hand-only riding and want the efficiency of a harness connection will get the most use from this accessory. Beginners still learning wing handling may want to develop their skills before adding a harness line to the setup. The elastic core provides a forgiving feel compared to a fixed-length line, reducing the likelihood of getting pulled off-balance by sudden gusts or movements.

Within Mystic's own wing accessory range, the Griplock Handles version sits alongside the Harness Lineset Soft Handles. The key difference is the attachment method: the Soft Handles version uses a lark's head connection designed for wings with soft handles, while the Griplock version clamps onto hard handles or booms. The Soft Handles variant is priced lower at roughly €19.99 compared to €29.99 for the Griplock, reflecting the additional hardware in the Griplock mounting system. Riders need to match the correct lineset to their wing's handle type — choosing the wrong version means an incompatible attachment.

In the broader market, harness lines for wing foiling are offered by several brands including Duotone and Ocean Rodeo, though dedicated elastic harness lines with a Dyneema sleeve remain a relatively specialized category. The Mystic Griplock sits at a moderate price point for wing harness lines and serves as a straightforward, single-purpose accessory rather than part of a larger integrated harness system.
