The Inno Sense bits come in three different models: soft, medium & hard. The mouthpieces are available in the versions; flexi, mullen and port. Bits from the Inno Sense line can be used for every horse and particularly suitable for young horses and/or horses with a sensitive mouth. The synthetic material is FDA approved, which means the material does not contain plasticizers and is non-toxic to people and animals. In addition, the flexi- and mullen model of the Inno Sense Bits line are solid because of the application of a core of stainless steel. Horses that are ridden with an Inno Sense Bit follow the hand easily and accept the bit smoothly.
