F-One Swivel Wrist Leash

The F-One Swivel Wrist Leash is a compact anti-twist device designed for wing foiling. Manufactured by F-One, a French brand with a long history in kite and wing foil equipment, this swivel mounts between the wing's leading edge loop and your wrist leash line. Its primary purpose is to prevent the leash from twisting and tangling during use — a common issue caused by repeated wing rotations and repositioning throughout a session. The swivel is categorized as a wing foil spare part and accessory within F-One's product line.

• Material: Stainless steel with Dyneema
• Cover: Neoprene sleeve for comfort and equipment protection
• Installation: Mounts without screws between the handleash and wing loop
• Compatibility: All F-One wing models (Strike, Swing, Origin)
• Reference number: 77211-9006

This swivel is aimed at any wing foiler who uses a wrist leash and wants to eliminate line twist. During a typical session, the wing gets flipped, rotated, and repositioned dozens of times, which can wind the leash cord into a tangled mess. Riders who session for extended periods or practice transitions and tricks will notice the most benefit, since those maneuvers generate the most cumulative rotation. Beginners and intermediates who frequently drop and re-grab the wing will also find that a swivel reduces frustration when retrieving a twisted leash.

The device is lightweight and compact enough that it adds minimal bulk to an existing leash setup. Because it mounts tool-free between the wing loop and the leash line, installation takes only a moment and requires no modification to the wing or leash.

F-One sells the swivel as a standalone accessory, separate from their complete Wrist Leash product. The full F-One Wrist Leash w/ Swivel — which includes a neoprene cuff, Spectra bungee cord, and an integrated swivel — retails for approximately $59–$64 depending on length and is available in sizes from 75 cm to 150 cm. The standalone swivel at $41.99 is intended for riders who already own an F-One wrist leash (or a compatible third-party leash) and want to add or replace the anti-twist component without buying an entirely new leash.

Among competitors, several brands offer leash swivels as integrated features rather than separate accessories. Duotone and Ozone, for example, build swivel mechanisms into their wing leash designs. F-One's approach of selling the swivel independently gives riders the flexibility to retrofit an existing setup. If you already have an F-One wrist leash and find the line tangling during sessions, this is the targeted fix rather than replacing the entire leash.
