The Cord Running Martingale is made of white nylon cord. The rings and swivel snap are stainless steel. This Martingale is adjustable both around the neck and to the cinch.
How it works: The running martingale is a very useful tool to aid a horse in learning proper head position as he learns collection. If adjusted correctly a martingale does not force the head to stay in any given position but allows the horse a guide for head placement through automatic release of pressure on the reins when correct head placement is achieved. This can make it easier for a horse to reach a more collected frame over time by allowing assistance with head position as rider teaches the horse to drive from behind.
A good rule of thumb for adjustment is to allow horse to stand comfortably, attach snap to girth D ring and extend the rings until they reach the throatlatch.
