The MB 33WL (wide low) mouthpiece was made specifically to meet the requirements of the USEF dressage rules, making this the only USEF dressage legal Level 3 mouthpiece. The port is 29mm high and generously wide, providing ample room for the tongue. Because the port is lower than the standard MB 33, the MB 33WL does not offer quite as much tongue relief but it is by far the most tongue relief available in a dressage legal mouthpiece.

Notes: For more tongue relief, see the MB 33. For similar tongue relief but some tongue pressure, see the MB 36 (USEF dressage legal).
An eggbutt is a traditional cheek style which keeps the mouthpiece from draping on the tongue, providing a more direct signal than the loose ring. The straight side of eggbutt will not pull through the mouth and does not pinch. For a more versatile version, see the eggbutt with hooks.
