Bit always remains in perfect position. Functions as snaffle with light rein pressure. Functions as mullen mouth when pressure increases. No pressure on palate or nutcracker effect. The contours of the mouth piece help the horse to find the correct head carriage. Horses that tend to get strong are corrected by a change of pressure points in the mouth. Specific shape of the D-rings bear on the outside of the mouth as a gentle correction to resistance to the direct rein. Association Approvals: Dressage: FEI, USEF, USDF, USEA Eventing: FEI, USEF, USEA Jumping: FEI, USEF, USEA These approvals are the best information we have at this time, but correctness standards are ever evolving. Competitors are reminded that they are responsible for the correctness of their tack. If a rider is unsure of the correctness of any tack, it is the rider’s responsibility to confirm their equipment with the steward or technical delegate.
