The Inno Sense Mullen is a straight bar that slightly bends forward. This mouthpiece is fabricated of elastic synthetic material (the same as flexi soft). The bit has a rigid core that makes the mullen bar not flexible but the material around it gives it a soft touch.
The rings of an eggbut cannot move separately from each other, so the riders aid is conveyed directly and the bit lies stable in the horse’s mouth. In addition, this cheekpiece does not pinch the corners of the horse’s mouth so bit rings are not necessary.
