The Potrera Saddle ( from the Spanish word for foal= potro) is preferably used in Spain for the starting and training of young horses because of the suede outer finish, a deep well balanced seat and good leg contact. The small front galery allows a standing trot as well as riding with shorter stirrup leathers. The hind galery gives a secure seat. 
A real Allround saddle. (although we'd personally prefer the 'Alta Escuela' saddle for its narrowerer seat and straighter flap style;-)
