Ion Leash Wing Core

The Ion Leash Wing Core is a straightforward wing leash from ION, a German watersports brand known for its harnesses, protection gear, and accessories across kiteboarding, windsurfing, and wing foiling. Available in both wrist and waist attachment styles, each offered in 4' and 5.5' lengths, the leash is designed to keep your wing tethered during sessions without adding unnecessary bulk or complexity. It sits within ION's "Core" accessory tier, which emphasizes functional reliability at an accessible price point.

The wrist version uses a neoprene cuff that wraps around the rider's wrist, while the waist version attaches to a hip belt or harness via a carabiner. Both variants share a clean, minimalist design focused on secure attachment and ease of use on the water.

The Ion Leash Wing Core suits beginner to intermediate wing foilers who need a dependable wing tether without the added features — and cost — of ION's coiled or safety-release leash models. The wrist option provides the most direct connection to the wing, making it easy to retrieve after a fall, and is a common choice for riders still building board starts and transitions. The waist option shifts the attachment point to the hip, which can reduce shoulder strain during longer sessions or when handling larger wings in stronger wind.

The 4' length keeps the wing close for quick retrieval in lighter conditions or smaller waterways, while the 5.5' length adds slack for riders who prefer more separation between their body and the wing — useful in choppier water where the wing can get tossed around. Either length works well for flatwater cruising and moderate coastal conditions typical of recreational wing foiling.

Within ION's leash catalog, the Wing Leash Core Wrist and Waist sit as the entry-level straight-cord options. Riders who want a coiled cord that retracts and reduces drag can step up to the Wing Leash Core Coiled Wrist, while those prioritizing safety can look at the Wing/SUP Leash Core Coiled Hip Safety, which adds a quick-release mechanism for emergency detachment. ION also offers a Wing Board Leash Core Hybrid Knee for tethering to the board itself rather than the wing.

In the broader market, the Ion Leash Wing Core competes directly with the Duotone Foil Wing Wrist Leash and the Dakine Fly Wing Wrist Leash, both of which occupy a similar price bracket and serve the same purpose. The ION's Dyneema-sleeved waist option and bungee wrist cord give it a slightly different material approach compared to competitors, but all three brands target the same everyday wing foiling audience.
