What is the purpose of the girth on a saddle?

The purpose of the girth on a saddle is to hold the saddle securely in place on the horse's back. A properly fitted girth wraps around the horse's barrel and attaches to the saddle, ensuring that it does not shift or slide during riding. This is critical for both the comfort and safety of the horse and rider, as a saddle that moves can lead to loss of balance and control. While other components and accessories may contribute to the overall fit and security of the saddle setup, the primary function of the girth is to provide that essential stability.
