Built for longboards and the way they move, this is a ten-foot longboard surf leash with a 7 mm cord and a hypalon ankle cuff. It is aimed at medium to large waves and at boards from roughly 9 ft upward: noseriders, logs, mid-lengths, the kind of board a surfer buys once and keeps for years. Put it in front of that customer and the conversation usually settles on the cuff, because the cuff is the part they will feel for the next three hours.
Ten feet is the longest surf leash length in our 7 mm hypalon group, so this model sits at the top of that ladder. It carries the same lightweight cuff and TPU cord as the shorter hypalon leashes, with the extra reach a 9 ft to 10 ft board needs when it is pushed around in the whitewater and the cord goes from slack to loaded in a second.
We are a surf leash manufacturer, and we supply this model as part of a wholesale programme — the sort of order that fills an accessory wall rather than a single hook. If you are building a leash range for a shop, a chain or a distribution territory, this is the 10 ft hypalon entry that sits between the 9 ft model and the heavier 8 mm builds.
The specification lists 60% TPU, 15% polypropylene, 10% neoprene, 10% nylon and 5% stainless steel, and that describes the whole leash rather than one part. The TPU is the cord, polypropylene and nylon form the strap and webbing sections, neoprene sits inside the cuff as padding, and the stainless content covers the swivels and the hardware anchoring the rail saver.
The cuff itself is hypalon, and it is the reason this model feels different from our neoprene-cuffed leashes. Hypalon is a dense synthetic rubber that does its job in a thin layer, so the cuff can be built light and still hold its shape when it is wet and being pulled at. Riders who dislike a bulky strap around the ankle are the ones who usually end up here.
The cord is where the work happens. A 7 mm TPU cord has to stretch and recover thousands of times without going slack or taking a permanent set, and it has to do that in salt water and sun. We build this one from top-grade TPU, the same material that runs through the rest of the hypalon and regular range. For context, our cords run from 5 mm on small-wave leashes to 9 mm on the SUP models; 7 mm is the middle of that spread, which is why this leash suits longboard conditions rather than heavy water.
Hardware is deliberately simple: two 316 stainless swivels and a streamlined rail saver, anchored so the load passes through the cord rather than through the stitching. CIMI has been a surf leash manufacturer since 2007, and the leashes, fins, traction and covers in the range are built in the same house — one supplier, one set of tolerances.
- Made for longer boards — A regular longboard ankle leash rated for medium to large waves or a longer board, which is exactly the gap a 6 ft or 7 ft leash leaves once the board passes 9 ft. - The ankle stays free — The ultra-light hypalon cuff with strong construction keeps material off the ankle; on a surfboard ankle leash you wear for hours, that is the difference between noticing it and forgetting it. - Cord that holds its line — Top-grade TPU at 7 mm gives stable strength under load and comes back straight instead of staying kinked. It is the same cord family used across the range, up to the heavier big wave surf leash builds. - Rail protection built in — The streamlined rail saver takes the wear where the cord meets the board, so the tail of a longboard does not get chewed by its own leash. - Marine-grade hardware — 316 stainless steel swivels let the leash turn with the rider rather than winding up, and 316 is the grade we specify for fittings that live in salt water. - Same build, order after order — Every run is assembled to one specification by the same surf leash manufacturer, so a repeat order matches the sample your buyers signed off.

|---|---|---|---|
| L22515H — 10 ft 7 mm hypalon (this model) | 7 mm TPU cord; ultra-light hypalon cuff; streamlined rail saver | Medium to large waves or a longer board | The lightest cuff option in the 10 ft 7 mm group; choose it when ankle bulk is the deciding factor on a longboard surf leash. |
| L22515 — 10 ft 7 mm regular | 7 mm TPU cord; double-padded neoprene cuff; streamlined rail saver | Medium to large waves or a longer board | Same length and cord as this model, but the cuff is padded neoprene rather than hypalon; for riders who prefer cushioning over a minimal cuff. |
