You can read about David Genedick's saddles on his website. "aboutthehorse.com" This is a cordura trail saddle. It is a #1 tree and 14.5 seat. It is measured from the front of the cantle at the bottom where your thigh hangs to the back of pommel against the front part of your thigh. It is made for a slight built short women. 5'4 or smaller. This is a very nice saddle. It has more flair in the front then conventional saddles. The #1 tree will fit like a semi quarter horse tree.
