17" seat, 7.5" gullet, medium tree, fits a majority of horses. This saddle is designed for light roping (never used for that though, only trail riding) team penning, sorting, ranch classes or as I used it, trail riding. Has exceptionally comfortable seat. Weighs 36 lbs, and has a 27" skirt. Brass fittings, and leather saddle strings. Also has a crupper ring, and oversized stirrups. I am charging 75.00 for shipping because it is not calculating correctly. I ship fed ex, and will be insured. If cost is less, I will refund the difference.
