Kaohi Inviz Hybrid Leash calf

The INVIZ Leash is a hybrid foil leash constructed with a high-strength polyurethane coil paired with a marine-grade bungee (Dyneema-style) for an innovative design inspired by downwind foiling experts from Hawaii, California, Texas, Oregon, Australia, and Japan.

This hybrid construction delivers an optimal combination of lightness, stretch, and strength, resulting in a quiet foiling experience that feels almost “invisible”—as if you’re hardly even wearing a leash.

Key Features:

• Coil section: The 7 mm polyurethane coil near the cuff provides stretch where needed while keeping weight and swing to a minimum.
• Bungee section: The Dyneema-style bungee gives lightweight length with strength and remains silent on the board, eliminating the typical clunking noise.
• No rail saver required: The bungee threads directly through the leash plug, creating a sleek, streamlined profile.
• Calf cuff connection: Designed specifically with a calf cuff attachment that keeps the leash secure while minimizing contact with the board.

Specs and Feel:

• Approximate total length of 4 ft (unstretched)
• 7 mm coil diameter
• Lightweight (around half the weight of many traditional leashes)

Ideal Use:

Primarily designed for downwind foiling, the INVIZ Hybrid also works well for wing foiling or SUP foiling in lighter conditions. For heavier or more demanding conditions, thicker or different leash styles might be recommended.
