This is a really cool saddle, with an interesting story attached. It's in great shape, and ready for a new home!
This saddle was designed by famous trainer, Monte Foreman and Slim Fallis - the stirrups are designed for maximum comfort and balance, no matter what the rider is doing, and the rigging is designed in such a way that there's no bulk under your leg from your latigo (think a double-rigged saddle, only better).
This is a great saddle for a young/green horse, and super for long days on the trail.
