The Horze Mullen Mouth Loose Ring Snaffle Bit discourages horses from leaning on the bit. Mullen style mouthpieces offer a mild effect evenly distributing pressure along the horse's tongue. Having a very stable feel in the horse's mouth, this is readily accepted by many horses and is a good option for sensitive horses who need a thinner mouthpiece due to a larger tongue or lower palate. This bit is legal for most dressage competitions where snaffle bits are allowed.
