Kaohi Inviz Mini Hybrid Calf Leash-Black/Yellow-7mm

The Kaohi Inviz Mini Hybrid Calf Leash is a compact foiling leash from Kaohi (Kāohi), an Encinitas, California–based brand whose name translates to "control" in Hawaiian. The Inviz Mini sits within Kaohi's hybrid leash line, pairing a continuous polyurethane coil section with a marine-grade bungee cord made from Dyneema-style material. This combination is engineered to minimize drag and noise on the water — two common complaints with traditional coil leashes used in foiling. The Black/Yellow colorway in the 7mm coil diameter represents the lighter option in the Inviz Mini range, which is also offered in an 8mm coil for riders who prioritize added strength over weight savings.

Developed with input from professional foil riders including Kane de Wilde and Tomo Murabayashi, the Inviz line reflects a stripped-down design philosophy. There is no bulky rail saver or grip handle; instead, the bungee end-loop threads directly through a leash plug or plug rope, reducing contact points that can catch water or create vibration while riding on foil.

• Unstretched length: 28 inches
• Coil section: 30 inches of continuous polyurethane
• Bungee section: 20 inches of Dyneema-style marine-grade cord
• Coil diameter: 7mm
• Cuff placement: Calf
• Approximate weight: ~4 oz (Inviz line)

Kaohi positions the Inviz Mini for advanced prone foilers and foil-assist riders who want a low-profile leash that stays out of the way during sessions. The short 28-inch unstretched length keeps the board close, which suits experienced riders comfortable managing board proximity during falls. Kaohi notes that the 7mm coil is the lightest option and appropriate for most riders, while the 8mm version is better suited to heavier conditions or more aggressive riding that involves airs, flips, or winging in waves.

Because of its compact size and quiet bungee section, the Inviz Mini appeals to riders who find longer coil leashes distracting — the bungee does not slap the water surface or create drag the way a full-length polyurethane coil can. That said, Kaohi does include a safety advisory: short leashes keep the board closer on all falls, which can increase the risk of contact, so pairing with a helmet and impact vest is recommended.

Within Kaohi's catalog, the Inviz Mini is the shortest and lightest hybrid option, sitting below the full-size Inviz Hybrid leash, which measures 3.5 feet of coil plus 20 inches of bungee and is marketed toward downwind foiling. Kaohi also produces the Double Coil leash — a patented design with an 8mm coil intended for wing foiling, SUP foiling, and surf foiling — and the Grip Leash, a more traditional straight or coiled surf leash with a built-in rail-saver handle. The Inviz Mini and the standard Inviz share the same hybrid coil-plus-bungee construction but differ meaningfully in total length and intended discipline.

For riders comparing across brands, the foiling leash market includes options from Dakine, Starboard, and FCS, though few competitors use a hybrid coil-and-bungee architecture. The Inviz Mini's design is relatively distinctive in its focus on combining stretch, silence, and minimal bulk in a short-leash format built specifically for prone and foil-assist use.
