Ocean & Earth Diamond Flex Longboard Leash Knee 9" Lime

Ocean & Earth Diamond Flex Longboard Leash Knee 9' — Comfort, control and durability for longboarding

The 9' Diamond Flex delivers a refined balance of flexibility and strength thanks to its advanced mould design with flex diamonds. This provides controlled flex and smooth transition from mould to urethane, reducing shock and keeping your board at a safe distance. A double-padded 38 mm anti-slip knee strap ensures comfort and a secure fit during long sessions. The extra-long railsaver protects your board’s rails and attachment point and is easily detachable when needed.

Safety and convenience features include a flex neck strap plug for 360° movement, a visible safety release pull tab for quick release in emergencies, and a Plug Buddy to help feed leash cord through the board plug. The leash uses premium controlled-stretch urethane — stretching more in larger waves to keep your board safely away — and ships with marine-grade dual anchor stainless swivels for tangle-free performance.
