Turtle Tactiowith Flex.Specifically engineered to accommodate the larger or sensitive tongue. Often negates the need to shut the mouth.FlexT Loose Ring.This bold TongueSMARTdesign focuses rein pressure to the central part of the tongue whilst diverting pressure away from the sensitive regions near the bars. The unique centralTurtlelink brings the proximal ends of the cannons to their closest separation possible. The Flexconcept of widening the surfaces that lie parallel to the plane of the tongue reduces the pressure further. With any kind of noseband the closed mouth easily accommodates the mouthpiece whose effective thickness in the region of the interdental space is the smallest in the Neue Schule range. To reward horses that want to work with you. Salox Mouthpiece, Stainless Steel Cheeks, Double Jointed Loose Ring.
