Fager Mia is suitable if you would describe your horse as the following;
Mia is a lightweight double-jointed bit with a special lockup function. The mouthpiece gives bar relief and locks upwards, which can be good for horses with a low palate and sensitive bars.
The bit doesn't lock forward like a normal lockup bit, which means that you won't get the stiff feeling of a straight bit.
The joints are rotated away from the tongue, which gives a more gentle, smooth pressure on the tongue. This can be good for horses that can overreact when you take the reins and need to keep the consistent contact through every movement. The lightweight material lets you keep a light feeling in the hand.
If you are searching for a gentle, kind bit for a sensitive horse, we would definitely recommend trying Fager Mia.
