The Medium Flex - mouthpiece consists of three layers:
A central core providing flexibility: this flexibility stimulates the same mechanoreceptors as a standard straight mouthpiece.
The body offering ergonomics: the mouthpiece responds to hand movements by adapting to the specific shape of the horse's mouth.
The outer layer providing cushioning: the medium cushioning transmits information from the hands, which is partially absorbed. This level of cushioning is intermediate between the Soft mouthpiece (very high cushioning) and the Strong mouthpiece (low cushioning).
