Its a 16.5 seat with Med/wide tree. It fits a buch of Diff horses pretty good. I have used it on a Tbred, QH, Friesian, Belgial X and Warmblood.
Its a nice saddle and nice comfy seat.
Its about 5 years old and in great condition. I keep it cleaned and conditioned and covered! I use the german conditioner on it to keep it soft.
These are what I use to clean it: Effax Leder Balsam to condition and Effax Leder Combi leather cleaner
