Gives a good lifting action without upper palate interference. A very unobtrusive design that sits well back in the mouth over the thicker, less sensitive part of the tongue. The “Slimma” mouthpiece incorporates a wide low tongue bridge designed to eliminate any chance of upper palate interference whilst leaving much more space for the bridoon – hence a thicker bridoon is an option for a horse that is tentative into the contact
