An English general purpose (GP) saddle is a type of equestrian saddle that is designed for all-purpose riding, including dressage, jumping, and cross-country. It is typically a medium-depth saddle with a relatively flat seat, and is suitable for a wide range of horse and rider types. Here are some of the main parts of an English GP saddle:

• Tree: The tree is the internal structure of the saddle that provides support and stability. It consists of a plastic or wood frame that is shaped to fit the contours of the horse’s back, and is typically covered with padding and leather.
• Pommel: The pommel is the front part of the saddle that rises up from the tree and forms the top of the saddle. It is typically rounded or pointed, and is used to help keep the rider in place when riding over rough terrain.
• Cantle: The cantle is the back part of the saddle that rises up from the tree and forms the rear of the saddle. It is typically higher and more pronounced than the pommel, and is used to provide support and stability for the rider’s back.
• Seat: The seat is the area of the saddle where the rider sits. It is typically padded and covered with leather, and is designed to provide a comfortable and secure riding position.
• Flaps: The flaps are the forward-facing panels of the saddle that extend down from the seat and cover the horse’s sides. They are typically longer and more flexible than the main panels of the saddle, and are used to provide the rider with a range of leg positions.
• Girth: The girth is a strap that runs under the horse’s belly and is used to attach the saddle to the horse. It is typically made of leather or synthetic material, and is tightened or loosened to ensure a secure and comfortable fit for the horse.
• Stirrup leathers: The stirrup leathers are the straps that run from the stirrups down to the girth and are used to hold the stirrups in place. They are typically adjustable, and are used to adjust the length of the stirrups to fit the rider’s leg length.
• Stirrups: The stirrups are the metal or plastic footrests that the rider places their feet in while riding. They are attached to the stirrup leathers and are used to provide balance and stability for the rider.
