The CIRCLE Y Square Swayback Contour Pad is designed to assist in fitting a saddle to a horse who experiences bridging across their back because of a lower than typical curve. Did you know a swaybacked horse can be young and underdeveloped, short coupled, or an older horse? When a horse has a dropped back, he needs pad support to fill in the gaps between his back and the saddle tree to help distribute the rider's weight to eliminate pressure points.
