The coiled leash itself is a superb quality 7mm thick coiled leash with a double swivel to prevent tangling and irritation. At maximum stretch the leash extends to 5.5ft which is achieved softly thanks to the excellent shock absorbing feature of the coil. We opted for a super strong 7mm thick leash to ensure that when the going gets tough this leash keeps performing. 
The features of this leash combine to make a fantastic overall wing foiling experience. Details such as the large do/undo loop prevent the leash from completely undoing which makes it a lot easier when on the beach with cold fingers. We also have the secure secondary velcro tab which prevents any spontaneous or unwanted undoing. 
Built to withstand the elements we opted to use a anodised aluminium buckle which is light but incredibly strong. When on the water you don’t notice it but when the going gets tough and you need something strong it is always there ready.
