4-S System®

Replacing the conventional sternum strap with a cord system allows for improved regulation and control.

The cord can be placed freely by leveraging the loop webbing system. This adjustment ability allows for easy regulation of the tension and quick changes on the move.

Lightweight cord and hooks transform the conventional static sternum strap into a dynamic tool with many dynamic options for use.
