Does your horse lean, pull or grab hold of the bit and run?
The Waterford Mouthpiece is fluid in the horse's mouth making it very difficult for the horse to grab on to it. It offers control while eradicating the pulling and fighting that causes damage.
The 3 ring gives multiple rein options depending on the amount of leverage needed for your horse. 
A suitable bit for Jumping and fast work.
This is NOT a bit for the novice horse or rider and should be used with knowledge.
