Set of Essentials windsurf harness lines that can be adjusted on the fly.

These harness lines feature a heavy-duty stainless steel buckle that allows length adjustments while sailing. Lines can be shortened by pulling on a dedicated loop while pressing the stainless steel buckle will unlock the line and allow it to be extended.

A transparent tube shows the current condition of the line that can prevent unforeseen breakage.

For installation, the boom tail needs to be removed.
