The Loose Ring Flexible Rubber Mullen Snaffle has a warmer feel to the horse's mouth, and is great for those horses that do not accept stainless steel very well. The rubber mouthpiece is particularly useful for horses with sensitive bars and/or tongues. The rubber mouthpiece is a milder alternative to stainless steel as the mouthpiece is normally thicker; therefore the pressure is distributed over a larger area. The rubber bits may be unsuitable if your horse is a larger breed which has thicker fleshy lips and/or large tongue. The loose ring may be useful if your horse leans on the bit, or takes hold, as the bit is always movable so the horse cannot take hold as easily as they could with a fixed cheek. T
