This is a size Piccalo, which is 16.5/17 inch english. I typically ride in an 18 dressage saddle and this saddle fits me perfectly. This saddle is only a year old, but unfortunately does not fit my new wide load horse. The base is designed for lighter hot blooded breeds ie Arabian type. Panels allow for spine clearance and are fully adjustable. The saddle only weighs 9lbs. Has 2 stirrup position options, close contact with a narrow twist and has the comfortable Coci padded seat great for those longer miles.
