What is the name of the channel that runs down the length of the saddle?

The gullet refers to the channel that runs down the length of the saddle, providing space for the horse's spine and ensuring proper fit. This design helps to prevent pressure on the horse's back by allowing for clearance and preventing pinching during movement. It plays a crucial role in both the comfort of the horse and the effectiveness of the rider's communication with the horse through the saddle.

While the stirrup is a metal or leather device that supports the rider's foot, the flap is the part of the saddle that lies under the rider's leg. The panel refers to the sections of the saddle that rest against the horse's body, typically filled with materials for cushioning. None of these options fulfill the function of providing the necessary channel down the saddle's length like the gullet does.
