The HP bungee leash has been used for years by freeride and wave kiters who don't unhook. HP bungee is dangerous because attached on the back of the harness. When you release the kite in safety by pulling CL QR system the bungee's QR system is almost impossible to reach and creates a critical safety issue.
By using JAY short leash attached to the DYNABAR sliding ring you eliminate the problem and obtain the advantage of being able to turn your body and for example get your board floating in the water behind you.
The JAY short leash can be used with any sliding system by adding a sliding stainless steel ring.
