Jumpin Loose Ring Double Jointed Bit Leather Tongue PortRings: 70 mm Barrels: 17 mm The loose ring bit is ideal for horses that may be sensitive at the corners of the mouth. The wide tongue port can offer real comfort to horses that show discomfort in the tongue area, especially with double jointed bits. This allows the horse to rest its tongue more comfortably, encouraging a more relaxed way of going. The leather wrapping offers a different feel and warmth in the horse's mouth compared to metal bits.
