Ocean & Earth Cold Water Allround Comp One-XT - 6ft Leash

A leash is the only thing connecting you to your board after a wipeout. Its length is a safety question, not a comfort one: too short and the board snaps back at your head coming out of a wave; too long and it gets a run-up before it reaches you. The rule is simple — match the leash to your board length or go slightly longer.

The One-XT cord is Ocean & Earth's top spec: moulded urethane with less permanent stretch for the same strength. In practice it springs back less under load and doesn't slowly turn into elastic that lets the board run too far.

Cold Water is the low-temperature build. Ordinary urethane stiffens in cold: it stretches less, kicks back harder into your leg and snaps sooner under shock load. This compound stays alive at low temperatures. 6 ft.

Who it isn't for. In the tropics it's money wasted — a standard cord does the same job in warm water. And the cuff is sized for a booted ankle, so it sits loose on bare skin.
