Blue Planet 5.5' Wrist Coil Wing Foil Leash

Can be attached to wrist with one hand, 5.5 ft coil leash length is good for most wings up to 6 M size, it's possible to extend it for use with bigger wings.

Can also be attached to waist belt leash.  The coiled leash helps keep the leash out of the way when getting up on boards and in transitions.   Not recommended for regular use in big surf, any coil leash will stretch out and loose tension if repeatedly stretched out forcefully if wing gets dragged by a big wave.
