The NEW M. Toulouse Aveline Pro-Hybrid Dressage saddle has a high external knee block that extends right up onto the skirt of the saddle. This block encourages the rider to keep from posting too far forward, and also provides additional support when riding horses that have the ability to "change direction without prior notice". Featuring a double V-Billeting system to equalize both front and back billet positions. Soft Double Leather needs no breaking in. Wool STP panels and Genesis Adjustable Tree for a custom fit.
