What additional function does a saddle pad serve regarding the saddle itself?

The saddle pad plays a crucial role beyond merely providing cushioning for the horse's back; it significantly contributes to the functionality of the saddle itself. By helping to keep the saddle clean and in place, the saddle pad protects both the horse and the saddle. It creates a barrier between the horse’s skin and the saddle, which reduces friction and minimizes the risk of saddle slippage during movement. This stability is essential for the safety and comfort of both the horse and rider, ensuring that the saddle maintains its optimal position throughout use.

While decorative aspects, weather protection, and weight considerations are important in their own right, they do not reflect the primary, practical role of a saddle pad in facilitating proper saddle function and maintenance. Therefore, the emphasis on cleanliness and secure placement highlights the primary importance of the saddle pad in equestrian practices.
