The Myler Loose Ring with Stainless Steel Comfort Snaffle Wide Barrell (MB02) is permitted at USEF/USDF competitions for use in a snaffle bridle. It is not allowed when used as the bridoon in a double bridle.
HAPPY MOUTH The Happy Mouth Shaped Mullen Mouth Loose Ring Snaffle is not allowed at USEF/USDF competitions because it does not meet the tongue relief requirements definition and it is not considered to be a true mullen mouth. Additionally the same mouthpiece in a curb bit is also not permitted.
The Happy Mouth Double Jointed Loose Ring Snaffle is allowed at USEF/ USDF competitions because only the center plastic piece rotates, not the entire linkage. Only a single rotating piece is permitted. It is allowed in a snaffle bridle and as the bridoon in a double bridle.
The Happy Mouth Plain Mullen Loose Ring is allowed in a snaffle bridle at USEF/USDF competitions. See Figure A, #6 of the USEF Dressage Rules. It is not allowed as a bridoon in a double bridle.
