Very good looking saddle. I found the seat sizes very big. I ordered the smallest size = 0 which should be equivalent of a 16.5?? seat although it was more like a 17??. I found the leather below expectation for that price, but I suppose this saddle is sold for it?fs design rather than leather.~nl~~nl~It has an air system in the panels which the horses like.~nl~~nl~The saddle lies better on a horse with a straight back than on one with a slightly curved back. It is important to keep in mind to prevent bridging.~nl~~nl~See the whole review here: http://www.used-saddles.info/tackreviews/bates-innova-dressage-saddle
