Kimblewick Prime bit from Beris.

Beris Prime sets a new standard in communication between horse and rider. The extremely soft mouthpiece provides even pressure over the tongue and bars. The integrated oval bit guards are carefully designed to prevent pinching risk at the corners of the mouth and provide lateral support. Kimblewick distributes pressure on the lower jaw, neck, and in the mouth. Three different options for rein placement depending on how much leverage effect you want.
