How does the Pro-Jump safety stud girth work?

The Pro-Jump Safety stud girth is equipped with an exclusive breastplate attachment system. Thanks to the safety stick, if the horse gets a hoof or a spike stuck in the breastplate when jumping for example, it will quickly come off the girth. The system will only be triggered if the breastplate is pulled downwards, so there is no risk of it coming off during a big jump or if the saddle moves backwards
