to prevent them from moving their jaw out of place & to prevent them from getting their tongue over the bit.
I personally use a figure 8 on my young 4 year old because when he was on the track he would grind his teeth against the bit and make him more nervous. Since off the track and more rides he doesn’t grind his teeth unless he’s scared or unsure of anything
Supports the facial structure for the horse. Doesn't allow them to cross their jaw and open the mouth to evade. However DO NOT use to strap the horses mouth shut
This is basically a grakle noseband that is supposed to keep the whole jaw closed when riding. It is one of the stronger nosebands for quite strong horses. As the horse's mouth is shut completely horse is more responsive to the rein&bit aids.
