Seat is stamped 18″ but measures smaller at 17.5″ flaps measure 14″ bar to bottom and 13.5″ across, the front gullet measures 4 3/4″- wide tree (you can use a Tad pad to help narrow down the fit if you need to).
2008 model. Saddle has both front + back blocks. The front blocks are the hard to find larger triangle ones. Very flexible front panels help to conform to wide shoulders. The leather is soft and you can just about roll the flaps. Outer pads are like soft little pillow that your knees will sink right into. There are no tears and no loose stitching and the bottom panels are in good shape. If you like very simple, minimal lightweight saddles this is one you will want to try. HORSES LOVE THESE!
