Kaohi INVIZ + Coil Cover Parawing Carabiner Leash-4'+30" x 7mm

The Kaohi INVIZ + Coil Cover Parawing Carabiner Leash is a hybrid foil leash built specifically for parawinging, combining a polyurethane coil section with a UHMWPE (dyneema-style) bungee cord. Designed in Maui by Cynthia Brown and sold through Board Meeting USA, the INVIZ line was developed in collaboration with professional foilers including Kane de Wilde and Tomo Murabayashi. This particular variant uses a carabiner clip for attachment to a waist belt or harness, and includes the brand's Coil Cover — a water-resistant spandex sleeve that sits over the coil section to prevent parawing bridle lines from snagging on the leash during use.

The 4'+30" sizing denotes approximately 3.5 feet of coiled polyurethane paired with 30 inches of UHMWPE bungee, yielding an unstretched length of roughly 42 inches and a total stretch exceeding six feet. The covered coil still expands and contracts normally, serving as the leash's shock absorber while the spandex tube keeps bridle lines from tangling around the coils. The product carries a US patent-pending designation.

This leash targets intermediate to advanced foilers who ride parawings and need a tangle-free board tether. Parawings use bridle lines that can easily catch on exposed coil leashes, making the Coil Cover a functional addition rather than a cosmetic one. Riders using a waist belt setup will find the carabiner connection straightforward to clip on and off.

The INVIZ line's hybrid construction weighs roughly 30 percent less than a comparable all-TPU coil leash, which appeals to riders focused on minimizing drag and noise while foiling. Kaohi does note that the INVIZ is not intended for heavy conditions — the brand recommends its 8 mm Double Coil or Continuous Coil leashes for more demanding sessions. This makes the INVIZ + Coil Cover a solid match for light-to-moderate wind parawing sessions where a quiet, low-drag connection to the board is the priority.

Within Kaohi's catalog, the INVIZ sits in the hybrid leash category alongside standard INVIZ models designed for downwind foiling and winging. The Parawing Coil Cover variant is a purpose-built extension of the INVIZ platform, adding the lycra sleeve specifically for parawing use. Kaohi also offers this same Parawing Coil Cover leash with two other attachment options — a calf cuff and a UHMWPE loop — at the same price point, letting riders choose based on their preferred connection method.

For riders who don't need the Coil Cover, the standard INVIZ leash is available at a lower price and suits downwind or wing foiling where bridle-line tangles aren't a concern. Riders looking for a heavier-duty option from Kaohi can step up to the Double Coil line, which uses thicker 8 mm cord and a double-coil design for greater shock absorption in bigger conditions.
