Circle Y Shoulder Bridge Pad for use under your Western Saddles at Marystack.com! With all the experience Circle Y has in making & fitting saddles they've developed this shoulder bridge pad to accommodate a horse with muscle atrophy, or hollows, behind the shoulder blades combined with prominent withers. Pad measures 15" long and is available in 3/4 inch and 1 inch thickness. The 3/4" pad is great for horses with a slight wither hollow while the1" memory foam shoulder bridge pad is ideal for horses with more pronounced hollows. It's designed to fit under your regular saddle pad and is made with memory foam so it fills in the gaps between the horse and saddle. This provides a much more comfortable saddle fit for the horse as it will disperse the rider's weight more evenly. Comes encasemened in black cotton Lycra for easy care.
