With this harness, moving becomes impossible. The black harness ties the arms far back on the back, making it absolutely impossible for the wearer to move them. The binder is attached over the shoulders and is fully adjustable. The buckles have a small round opening through which a lock can be inserted. This gives the ultimate control. At the bottom of the binder, a strong D-ring is attached to which you can attach your favourite bondage ropes and chains.
